“Step 11: Complete the Installation” on page 1-25
Before You Install
To run the installer, you need:
• Your email address and your MathWorks Account password. You will need
them to log in to your account during installation. If you have multiple
licenses associated with your account, know which license you want to
install.
If you don’t have a MathWorks Account, you can create one during
installation. You must have an Activation Key to create an account.
An Activation Key is the unique code that identifies a license. Ask the
administrator of the license for the Activation Key.
• Make sure you have the correct permissions to perform the installation. If
you have questions about this, ask your system administrator.
1-3

Note While you use an administrator account or root privileges to
install the software, you typically do not want to activate the software
for a privileged user. Specify the non-privileged end user who will use
the software when you activate it. Running MATLAB as a user with
administrator privileges or root privileges is not recommended.
- Windows — Get the name and password of the administrator account
on your computer. The installer modifies the system registry during
installation.
- Linux — Get the root password. You can install MATLAB® software
without superuser privileges, however, it limits certain installation
options. For example, if you want to set up symbolic links to the matlab
command, install product files in a protected folder, or edit the system
boot script, you must have superuser status.
- Macintosh — Get the name and password of the administrator account
on your computer. The administrator account is the user account you
set up when you configured your Macintosh® system; this is not your
MathWorks Account. During installation, you must enter this name and
password in the Authenticate dialog box.
• Consider disabling virus-checking software and Internet security
applications on your system during installation. These applications can
slow the installation process or cause it to appear unresponsive (or to hang).
1-4

If you do not have an Internet connection during installation, see “Installing
and Activating Without an Internet Connection” on page 1-40. If you need
to perform a network server or client installation, see Chapter 2, “Installing
Network License Options”.
If You Are Upgrading an Existing Installation
If you are upgrading your MATLAB installation to the latest release,
MathWorks recommends that you install the new version in a new installation
folder. This is recommended when upgrading an installation of a prerelease
version of the software as well. You do not need to delete an existing MATLAB
installation before installing this release. Each release is independent of
previous releases and you can run multiple releases on the same system.
Note If you choose to overwrite an existing installation from a prior release,
the installer deletes all the products in your installation folder and installs
only those products included in your current license. This avoids potential
product incompatibilities. For example, if your existing installation includes
10 products, but your current license only includes 9 of those products, your
MATLAB installation only includes the 9 products in your current license.
Step 1: Start the Installer
The method you use to start the installer depends on your platform.
• Windows — Insert the DVD into the DVD drive connected to your system
or double-click the installer file you downloaded from the MathWorks Web
site. The installer should start automatically.
• Macintosh — Insert the MathWorks DVD into the DVD drive connected
to your system or download product files from the MathWorks Web site.
When the DVD icon appears on the desktop, double-click the icon to display
the DVD contents, and then double-click the InstallForMacOSX icon to
begin the installation.

• Linux — Insert the DVD into the DVD drive connected to your system
and execute the following command:
/path_to_dvd/install &
1-6

If you are installing from downloaded files, extract the installer from the
archive file and execute the installer command:
./install
Depending on how your system is configured, you might have to mount the
DVD first. Make sure you mount it with execute permissions, as in the
following example. Note that the name of the DVD drive might be different
on your system.
mount -o exec /media/cdrom0
Step 2: Choose Whether to Install Using the Internet
Choose whether you want to install using an Internet connection or without
using an Internet connection. If you are connected to the Internet, leave the
Install using the Internet option selected (the default) and click Next.
During installation, you log in to your MathWorks Account, select the license
you want to install, and follow the prompts on the other installer dialog boxes.
This is the easiest way to install.
If you are not connected to the Internet connection during installation, choose
the Install without using the Internet option and click Next.
1-7

Select this option to install products (recommended).
Click Next.Select this option if
you do not have an

If you do not have a MathWorks Account, select the I need to create a
MathWorks Account option and click Next. You can enter the data needed
to create one.
If you have a File Installation Key, select the Provide File Installation Key
option and enter your key. A File Installation Key identifies the products you
can install. The administrator on a license can retrieve the File Installation
Key from the License Center at the MathWorks Web site. If you specify a File
Installation Key, the installer skips the license selection step.
If you have an account, enter your
email address and password.
If you need
to create an
account, select
this option.
Click Next. If you have
a File Installation
Key, enter it here.
1-11

Creating a MathWorks Account
To create an account, enter your email address, first name, last name, and
password. You must also provide an Activation Key because a newly created
account does not have any licenses associated with it. The Activation Key
identifies the license you want to install. The administrator contact on the
license can retrieve the key by visiting the License Center at the MathWorks
Web site. Click Next to send this information to MathWorks and create your
account.
Enter your e-mail address.
Enter Activation Key.Click Next. Enter first name and last name.
Create a password for your account.
Note When you create a new MathWorks account, you must verify your
e-mail address before you can proceed with installation. Before you click Next
in the E-mail Verification Required dialog box, go to your e-mail program,
open the message sent to you by MathWorks, and click the verification link.

• Information identifying the license option and the activation type. If an
activation type has not yet been set on the license, the word “Unset”
appears.
If you want to install products on a license that is not associated with your
MathWorks Account, select the Enter an Activation Key for a license not
listed option, enter an Activation Key, and click Next. An Activation Key is
the unique code that identifies a license. It can be used to activate a license
and also allows licensed end users to associate their MathWorks Account with
a license. Ask the administrator of the license for the Activation Key.
1-14

1-15

Enter activation key.
Click Next.
1-16

Step 6: Choose the Installation Type
In the Installation Type dialog box, specify whether you want to perform a
Typical or Custom installation and click Next.
• Choose Typical if you have an Individual or Group license and do not need
to specify which products you want to install and do not need to access any
installation options.
• Choose Custom if you need to specify which products to install, need access
to installation options, or need to install the license manager (network
license options only).
Select Typical or Custom.
Click Next.
If you choose a Typical installation, the installer skips the product selection
and installation options steps.
1-17

Step 7: Specify the Installation Folder
Specify the name of the folder where you want to install MathWorks products.
Accept the default installation folder or click Browse to select a different one.
If the folder doesn’t exist, the installer creates it.
On Macintosh systems, the installer puts the MATLAB application package,
MATLAB_R2012a.app, in the Applications folder, by default.
When specifying a folder name, you can use any alphanumeric character and
some special characters, such as underscores. The installer tells you if the
name you specified includes any characters that are not permitted in file
names. If you make a mistake while entering a folder name and want to start
over, click Restore Default Folder. After making your selection, click Next.
Specify name of installation folder.
Click Next.
1-18

Step 8: Specify Products to Install (Custom Only)
If you are performing a custom installation, you can specify which products
you want to install in the Product Selection dialog box. This dialog box lists all
the products associated with the license you selected, or with the Activation
Key or File Installation Key you specified. In the dialog box, all the products
are preselected for installation. If you do not want to install a particular
product, clear the check box next to its name.
After selecting the products you want to install, click Next to continue with
the installation. The installer checks if any of the products you selected
depend on other products. If there are product dependencies that are not
satisfied, the installer issues a warning. Consider adjusting your product
selection.
Select the products you want to install.
Click here to select or
clear all product check
boxes.
Click Next.
1-19

If you asked the installer to determine if newer versions of your products are
available at the MathWorks Web site, the installer displays both the newer
version and the version available on the product DVD in the product list. By
default, the latest version is preselected for installation. When there are
product updates available, the Product Selection dialog box includes a column,
called Source, that identifies whether the product will be installed from the
DVD or must be downloaded. For product downloads, the Source column
includes information about the size of the download file. The dialog box also
includes information about the total download size for all the products you
select.
If you do not want to download any product updates, click Select local
versions only. This clears the selection of all the product downloads in the
product list. If you want to install only the latest versions of all products,

package, right-click (or Ctrl+click) the package and select Show Package
Contents.
Step 2: Choose Whether to Activate Automatically
or Manually
Activation is a process that verifies licensed use of MathWorks products. This
process validates the license and ensures that it is not used on more computers
or by more users than allowed by the license option you have acquired.
If you let the installer start the activation application, and you were logged in
to your MathWorks Account during installation, your log-in session continues
into the activation process. Simply click Next to proceed with activation.
Click Next.
If you were not logged to your MathWorks Account during installation, or you
started the activation application independently, you must choose whether
to activate automatically or manually. If you are connected to the Internet,
leave the Activate automatically using the Internet option selected.
MathWorks recommends activating automatically. The option to activate
1-28

manually is useful if you do not have an Internet connection. Note that you
need a License File to activate manually.
If you have an Internet connection,
leave this option selected.
If you do not

supports several types of proxy configurations: Basic authentication and
1-29

Digest authentication. See “Accessing Activation Options” on page 3-2 for
more information.
Note If you continued with activation immediately after installation, and
you logged in to your account during installation, the activation application
skips this step.
Enter the email address and password of your MathWorks Account and click
Next. The activation application contacts MathWorks to retrieve the licenses
associated with your account.
If you do not have a MathWorks Account, select the I need to create an
Account option and click Next.
If you already have a License File, select the Provide the path to the
License File option, specify the complete path to the file, and click Next.
Your License File identifies the products you can run. You may have received
this License File from the administrator of the license. After specifying the
License File, the activation application skips all the subsequent steps in the
process and goes directly to the Activation Complete dialog box.

Step 5: Select an Activation Type
Note If the license you installed (or selected in the previous step) has the
activation type preset, the activation application skips this step.
Select an activation type for your license. If you want to ensure that you are
the only person who can use the software, select the Standalone Named
User option. If you want to share the installation for nonsimultaneous use by
several people, choose the Designated Computer option.
After making your selection, click Next to proceed with activation.
Click option to choose activation type.
Click Next.
1-35

Step 6: Specify the User Name
Note If you picked the Designated Computer activation type for the license,
the activation application skips this step. You do not need to specify a user
name.
If you selected the Standalone Named User activation type, you must specify
the operating system user name of the person who will use the software.
The Standalone Named User activation type limits use of the software to a
particular user on a particular computer. MathWorks uses the operating
system user name to identify this person. The operating system user name
is the ID through which a user gains access to a computer. This ID is also
known as the computer login name. To use MathWorks software, you must be
logged into the computer as the user name that you specify.
By default, the activation application fills in the user name of the person
running the activation application. To accept this default, leave the I will use
the software option selected and click Next. If you used your administrator
account to install the software but will use another account to access the
software, you can specify that user name here.
If you want to activate the license for someone else, select the Someone
else will use the software option, specify their email address, name, and
operating system user name, and click Next. The activation application looks
for their MathWorks Account or creates an account for them. This option can
be useful for system administrators activating the software for other users.
1-36

Leave this option selected
if you will use the software.
Specify the user name of the
person who will use the
software.
Specify information
about the person
who will use software.
Click Next.
Step 7: Confirm Your Activation Information
If all the information displayed is correct, click Activate.
To activate an installation, MathWorks creates a License File that is locked to
the computer, and to a particular user if you chose the Standalone Named
User activation type, and copies this License File onto your computer. This
License File enables you to run MathWorks products on your computer.
MathWorks also keeps a record of the activation in MathWorks systems.
1-37

Verify all your activation data.
Click Activate.
Step 8: Complete the Activation
After activating your installation, click Finish to exit the activation process.

Updating Your License
Throughout the term of your license, your MATLAB installation periodically
contacts MathWorks to verify that your license is up-to-date. If your license
is up to date, the validation process is transparent. If it determines that
you need to update your license, the validation process displays a dialog box
giving you the option to update your license.
You can disable validation at the License Center at the MathWorks Web site.
See the License Center Help for step-by-step instructions.
Setting Your MATLAB Startup Folder
If you start MATLAB using the shortcut on your desktop, the initial current
folder (or startup folder) is My DocumentsMATLAB. (You can choose to have
the installer create this shortcut at “Step 9: Specify Installation Options
(Custom Only)” on page 1-22.) To learn how to specify the startup folder, see
the MATLAB Desktop Tools and Development Environment documentation.
Setting Up MATLAB Environment Options
To include welcome messages, default definitions, or any MATLAB
expressions that you want executed every time MATLAB is invoked, create a
file named startup.m in the matlabroottoolboxlocal folder. Every time

Deactivating a License
Deactivating a license renders the MathWorks software unusable on a
particular computer. Deactivation can be a useful way to manage usage of
the software on multiple computers. For example, if you want to install and
activate the software on a new computer, and you’ve already performed all the
activations allowed by your license, you can deactivate one of your existing
installations to enable activation on your new computer.
The deactivation process has two parts: the license must be deactivated on
your computer and must also be deactivated in MathWorks systems. If you
have Internet connectivity, the MathWorks deactivation application can take
care of both parts of the process. If you do not have Internet connectivity, the
deactivation application disables the software on your computer and gives you
a deactivation string. To complete the deactivation process, you must visit
the MathWorks Web site, log in to your account, and deactivate using the
deactivation string. When you deactivate a license, you deactivate all the
installations of that license on a particular computer.
Note Deactivating a license and removing the software are separate
activities. You can deactivate a license without removing the software
from your computer. For information about removing an installation, see
“Removing (Uninstalling) MathWorks Products” on page 1-61.
To deactivate a license on your computer, follow this procedure:
1 Start the deactivation application using any of the following methods.
• Choose to start deactivation after running the uninstaller.
• Choose to start deactivation after a validation check that finds the
installation is inactive.
• Choose the deactivate option from the Help > Licensing menu in the
MATLAB desktop.
• Navigate to your MATLAB installation folder. matlabroot, and launch

2 Installing Network License Options
Setting Up a Network Configuration
Depending on your network configuration, you might have to perform
multiple installations:
• Installing the license manager on a server — For network
installations, you must install the FLEXnet license manager to control
product access. You install the license manager on a server that is available
to all your network users, referred to in this documentation your license
server.
If you are already running the FLEXnet license manager at your site and
are familiar with licensing, you can copy the daemons into the proper
folders and use your existing installed license manager. See “Installing the
License Manager on a Server” on page 2-4 for step-by-step instructions.
• Installing MathWorks products on a server — If your configuration
calls for users to use MathWorks products from a central location, rather
installing the products on their local system, you must install the product
files on a server. If this server is the same system as your license server (it
doesn’t have to be), you can install MathWorks products at the same time
as you install the license manager.
• Installing MathWorks products on each client system — If your
network configuration calls for users to install MathWorks products on
their own systems and only access the license server over the network, then
you must install the product files on each system. The client systems must
be able to connect to the license server over a network. See “Installing
MathWorks Software on Client Systems in Network Configurations” on
page 2-27
Instead of performing the installation procedures interactively, providing
the information requested by each dialog box, you can run the installer
noninteractively. In this mode, you enter into a properties file all the
information you would normally provide using the installer dialog boxes.
For more information, see “Installing Noninteractively (Silent Installation)”
on page 2-59.
2-2

Setting Up a Network Configuration
Note For the network license options, you do not need to run the activation
application to activate the software. Instead, you activate the license server
in the License Center at the MathWorks Web site before you install. Client
installations do not need to be activated.

“Step 10: Configure the License Manager” on page 2-20
Note If your configuration calls for the license manager and MATLAB
software to run on the same server, you can perform both installations at
the same time.
Before You Install
Before you run the installation program:
• Make sure you have your e-mail address and your MathWorks Account
password handy. You will need them to log in to your account during
installation. If you have multiple licenses associated with your account,
know the number of the license you want to install.
installation. However, you must have an Activation Key. An Activation
2-4

Key is the unique code that identifies a license. It is used to activate the
license. The Activation Key also allows licensed end users to associate their
MathWorks Account with a license. Ask the administrator of the license for
the Activation Key.
• Have your License File handy. For network configurations, you activate the
license before you run the installer on the server. Visit the License Center
at the MathWorks Web site, providing the host ID of the computer on which
you intend to run the license manager. MathWorks creates a License File
that you can download from the License Center. You specify this License
File during installation of the license manager on the server. Only the
administrator contact on a network license option can activate the software.
• Shut down the license manager, if it is running. See “Starting the License
Manager” on page 2-49 for more information.
2-5

• Consider disabling virus checking software and Internet security
These applications can slow down or cause the installation process to
appear to become unresponsive (hang).
You only need to install the license manager once at a site. For information
about installing MathWorks software on clients, see “Installing MathWorks
Software on Client Systems in Network Configurations” on page 2-27.
folder. You should also install into a new folder when upgrading an
installation of a prerelease version of the software, as well. You do not need to
delete an existing MATLAB installation before installing this release. You
can run multiple releases of MATLAB on the same system.
Note If you are installing the license manager in a new folder, you should
either remove the license manager service before running the installer or
choose to not configure the license manager. You cannot run two license
managers at the same time, even if they are in different folders.

Step 8: Specify Products to Install
To install the license manager, you must select the license manager in the
product list. By default, it is not selected for installation.
If you are only installing the license manager on your server, clear the
check boxes next to the other products. If you are setting up a remote access
configuration where users will run MathWorks products on a central server,
and this central server is your license server, leave all the other products
in the list selected for installation.
After making your selections, click Next to proceed with the installation.
After clicking Next, you might receive a message telling you that one or
more of the products you selected depend on other products. See “Product

you retrieved from the License Center at the MathWorks Web site.
Specify full path of License File.
Click Next.
License File Processing on Server
When you install the license manager on a server, you must specify the
location of the License File you retrieved from the License Center at the
MathWorks Web site. The installer performs the following processing of this
License File:
• Makes a copy of your License File, naming it license.dat, and puts this
copy in the etc folder of your MATLAB installation folder.
2-19

• Adds a SERVER line and a DAEMON line to the file. The SERVER line identifies
the server (host and port number). The DAEMON line identifies the name of
the license manager daemon.
• Stores the processed License File in matlabroot/etc, where matlabroot is
your MATLAB installation folder.
Step 10: Configure the License Manager
You configure the license manager in different ways, depending on which
platform you are installing.
Windows Systems
MathWorks recommends configuring the license manager service. This
provides automatic startup at system boot time and centralizes administration
of the license manager through the Windows Services control panel. To
review the default license manager configuration settings, click View Default
Settings. If you choose not to configure the license manager service, you
can do it later.
Note If you have an existing license manager that you want to continue to
use until you install this new one, select the Do NOT configure license
manager service option. The installer still installs the license manager
files. After installation, you can stop your existing license manager and start
your new license manager.
2-20

Choose whether to configure license

configuration settings.
Click Next.
Macintosh Systems
To add an entry for the license manager to your system Startup Items folder,
leave the option selected and click Next. Specify the user name that will own
the license manager process. For security reasons, this name cannot be root.
2-21

Click Next.
Enter the user name that owns
the license manager process.
Choose whether to configure the license
manager to start automatically at startup time.
2-22

Click Install.
The installer includes information about how to start the license manager
on your server. If you installed other products, you might also see some
additional product configuration and product update information.
2-23

Click Next.
2-24

When the installer finishes, it displays the Installation Complete dialog box.
Click Finish to exit the installer.
If you installed the license manager as a service, MathWorks recommends
that you restart your computer now. The license manager must be running
to start MATLAB on client systems. As a service, the license manager gets
started automatically at system boot time.
Click Finish.
2-25

Making Products and Licensing Information Available to
Clients
After you install the license manager on your server, you must provide users
who want to install MathWorks products on their computers with:
• Licensing information — Give users a copy of the License File that was
processed during installation of the license manager on your server. For
information about this License File, see “License File Processing on Server”
on page 2-19.
Note Do not give users performing client installations a copy of the
original License File you created from the licensing e-mail. They can’t use
the licensing information in this form. Also, do not forward to users the
licensing e-mail you received from MathWorks.
Depending on how you provide access to product files, you must also give
users performing client installations a File Installation Key for the license
or the Activation Key for the license.
• Access to product files — There are several ways to make product files
available to users performing client installations. You can share the
MathWorks product DVD with users. You can also download the product
files and make the files available on a server that is accessible to all
clients. For these scenarios, users will need a File Installation Key to
install products.
If users performing client installations have MathWorks Accounts, you can
give users the Activation Key for the license and let them log in to their
accounts during installation and download product files from MathWorks.
• Installation instructions — Give users a copy of the instructions
in “Installing MathWorks Software on Client Systems in Network
Configurations” on page 2-27. Do not give them the license manager
installation instructions because this might confuse them.

MathWorks Account with a license. Ask the administrator of the license for
the Activation Key.
• Client installations must use the License File that was processed during
installation of the license manager on your server. The installer adds
information to the License File during installation that clients need.
Depending on how your license administrator intends to provide you with
access to product files, you will need either a File Installation Key or an
Activation Key. Ask your license administrator for details.
• Shut down the license manager, if it is running. See “Starting the License
Manager” on page 2-49 for more information.

For general information about post-installation tasks, see .
Starting the License Manager
To start MATLAB software on a client computer, the license manager must
be running on the server. On Windows and Macintosh systems, the installer
configures the license manager to start automatically when you start your
system. (On Linux systems you must edit the system boot scripts–see “Editing
Boot Scripts on Linux Systems” on page 2-51 .) If you accepted this default
configuration, the easiest way to start the license manager is to reboot the
computer on which you installed the license manager. There are several other
ways to start the license manager, depending on your platform. The following
section describe these methods.
• “Windows Systems” on page 2-50
• “Linux and Macintosh Systems” on page 2-50
Note The user name associated with the license manager process should
be a user that is defined locally on the system, not defined on a network.
The license manager will only start up properly if the user name can be
found during the startup process on the computer, before network users are
available.
2-49

Windows Systems
You can start the license manager on Windows systems using any of the
following methods:
• Use the Windows Services control panel to start or stop the
license manager, if you chose to configure it as a service during
installation. On the Windows Start menu, select Settings > Control
Panel > Administrative Tools > Services
• Use the license management utility, lmtools.exe, included in your
MATLAB installation in the matlabrootetcwin32 or win64 folders.
Launch the lmtools.exe application and select the Start/Stop/Reread
tab.
Linux and Macintosh Systems
To start the license manager daemons on a Linux or Macintosh system,
execute the lmstart script (located in the matlabroot/etc folder), where
matlabroot represents the name of your top-level MATLAB installation
folder. The lmstart script stops any currently running daemons and starts
new ones.
To run lmstart on a Macintosh systems, open a terminal window using the
Terminal application (found in /Applications/Utilities) and navigate to
the /etc folder in your MATLAB installation folder:
cd /Applications/MATLAB_R2011a.app/etc
Note A user other than root should run the lmstart script because it
is a security risk to run any program as root that does not require root
permissions. The license manager (lmgrd) does not require root permissions.
If you must start the license manager as root, use the su command to start
lmgrd as a nonprivileged user:
su username -c "lmgrd -c license_file -l /var/tmp/LM_TMW.log"
where username is a nonprivileged user.
2-50

Editing Boot Scripts on Linux Systems
To configure the license manager to start automatically at boot time on
Linux systems, edit the system boot script on the computer on which you
installed the license manager. The MathWorks provides a file, named
matlabroot/etc/flexnet.boot.linux, containing the set of Bourne shell
commands required to start the license manager. The following sections
describe how to insert these Bourne shell code fragments for all supported
platforms:
1 Log in as root.
2 Create the following links, if they do not already exist.
ln -s matlabroot/etc/lmboot /etc/lmboot_TMW
ln -s matlabroot/etc/lmdown /etc/lmdown_TMW
3 Make a copy of the boot script file, using the command appropriate for your
platform in the following table, for both 32-bit and 64-bit systems.
Distribution Command
Debian or
SUSE
cp matlabroot/etc/flexnet.boot.linux
/etc/init.d/flexnet
Red Hat or
Fedora Core
cp matlabroot/etc/flexnet.boot.linux
/etc/rc.d/init.d/flexnet
4 Edit the copy you made of the boot script file, named flexnet in the
previous step, replacing the username argument to the lmboot_TMW script
in the code with a valid user name, other than root. For security reasons
the license manager daemons cannot be owned by superuser.
5 Look in /etc/inittab for the default run level.
6 Create a link in the rc folder associated with the default run level. The
following table lists the appropriate commands for supported Linux
distributions for both 32-bit and 64-bit systems, using run level 5 to
illustrate.
2-51

Distribution Command
Debian cd /etc/rc5.d;
ln -s ../init.d/flexnet S90flexnet
Red Hat or
Fedora Core
cd /etc/rc.d/rc5.d;
ln -s ../init.d/flexnet S90flexnet
SUSE cd /etc/init.d/rc5.d;
ln -s ../flexnet S90flexnet
7 Make sure that the license manager boot scripts start at the very end of
the boot sequence. For the license manager to start correctly, the network
must already be running. Use whatever mechanism your version of Linux
provides to ensure the boot sequence.
For example, on systems running SUSE version 10, you can specify the
boot sequence in the .depend.start file in the /etc/init.d folder. To
ensure that the license manager is started after networking, append the
following to the end of /etc/init.d/.depend.start file:
flexnet: network
On some systems, simply renaming the S90flexnet symlink, created in
step 6, to a higher number, such as S99flexnet, will ensure that the license
manager starts after networking is running.
Configuring the License Manager to Start
Automatically on Macintosh Systems
If, during installation, you chose not to configure the license manager to start
automatically at system startup, perform these steps to configure it yourself.
1 Navigate to the top-level /Library folder.
2 If a folder named StartupItems does not exist in this folder, create it.
3 Copy the matlabroot/etc/MATLABLmgr folder into the StartupItems
folder.
4 Run the config_lm.sh script, which is included in the /etc/MATLABlmgr
folder. Open a terminal window (run the Terminal program in
2-52

/Applications/Utilities) and in the Terminal window enter the
commands:
cd /Library/StartupItems/MATLABLmgr
./config_lm.sh
5 Enter the name of the folder where your MathWorks products are
installed. For example, if you installed MathWorks products in
/Applications/MATLAB_R2011a, enter:
/Applications/MATLAB_R2011a
6 Enter your user name. The script uses the user name returned by the
whoami command as the default. Accept the default or enter a different
user name.
7 When the script finishes, restart your machine.
During startup, the message Starting MATLAB License Manager should
appear on the screen. If you have difficulty starting the license manager, see
Chapter 3, “Troubleshooting”for more information.
Disabling Automatic Startup of the License Manager
If you do not want the license manager to start automatically at startup, you
can disable it. To disable the MATLABLmgr script:
1 From the Finder, select Go To Folder from the Go menu.
2 In the Go to folder dialog box, enter
/Library/StartupItems/MATLABLmgr
and click Go. A window titled MATLABLmgr appears, containing several files.
3 Rename the file StartupParameters.plist to
StartupParameters_disabled.plist.
You can re-enable the license manager to start at startup by following steps
1 to 3 above and renaming StartupParameters_disabled.plist back to
StartupParameters.plist.
2-53

Removing the License Manager on Macintosh Systems
1 From the Finder, select Go To Folder from the Go menu.
2 In the Go to folder dialog box, enter:
/Library/StartupItems/MATLABLmgr
and click Go. A window titled MATLABLmgr appears, containing several files.
3 Drag the MATLABLmgr folder to the trash, and then select Empty Trash
from the Finder menu.
Managing the License Manager
This section describes several utilities provided by FLEXnet licensing that you
can use to manage the license manager. For detailed information about these
utilities, see the License Administration Guide, included in PDF format in
your MATLAB installation (matlabrootetcLicenseAdministration.pdf).
• “Using the LMTOOLS GUI (Windows Systems Only)” on page 2-54
• “Using the License Manager Command Line Utilities” on page 2-55
Using the LMTOOLS GUI (Windows Systems Only)
On Windows systems, FLEXnet Publisher licensing includes a graphical user
interface (GUI), called LMTOOLS. Using LMTOOLS, you can perform many
license management tasks, such as:
• Getting the status of the license manager
• Starting and stopping the license manager
• Configuring the license manager as a service
To illustrate, the following example shows how to use the LMTOOLS GUI to
see the current status of the license manager:
1 Start LMTOOLS by double-clicking the lmtools.exe file in the
matlabrootetc$ARCH folder, where matlabroot is your MATLAB
installation folder and $ARCH is a platform-specific subfolder, such as win32.
2-54

2 Click the Server Status tab.
3 Click the Perform Status Enquiry button. LMTOOLS displays the same
information as if you had entered the command lmutil lmstat -a.
Using the License Manager Command Line Utilities
FLEXnet licensing includes a set of license management utilities that you can
use to start, stop, and monitor the license manager.
On Windows systems, FLEXnet packages all the utilities in a single,
command-line executable called lmutil.exe. This program is available in
the matlabrootetc$ARCH folder, where matlabroot is your MATLAB
installation folder and $ARCH is a platform-specific subfolder, such as win32.
For example, to run a status check of the license manager, open a DOS
command window and run lmutil specifying lmstat as an argument:
lmutil lmstat -a -c "C:Program FilesMATLABR2012aetclicense.dat"
2-55

The -a option requests a verbose listing. You must also include the-c option
to specify the License File to use. You must use this with every lmutil option.
If your installation path contains spaces, enclose the path in quotes. The
following is a portion of the information returned.

noninteractively, see “Running the Uninstall Program Noninteractively” on
page 2-61.
If you have many installations of MATLAB software to perform, and the
information you need to enter for each installation is the same, you can
put this information into a properties file and run the MathWorks installer
noninteractively. You specify the properties file on the command line
when you launch the installer and the file provides the installer with the
information that you would otherwise provide interactively, using the installer
dialog boxes. Noninteractive installation (also called silent installation) can
save time and prevent errors.
Using an Installer Properties File
Note You need a File Installation Key to use an installer properties file.
To run the installer noninteractively, perform these steps:
1 Create an installer properties file.
Make a copy of the installer properties file template, named
installer_input.txt, located in the top-level folder on the MathWorks
DVD.
For example, on a Windows system, you might execute this command:
2-59

copy Z:installer_input.txt C:tempmy_installer_input.txt
2 Open your installer properties file using any text editor, and enter values
for all the specified parameters. For example, to specify where you want to
install products, set the value of the destinationFolder= parameter to the
full path of the installation folder.
destinationFolder=C:Program FilesMATLABR2012a
The installer properties file template contains descriptions of each
parameter along with valid values. Specify your File Installation Key as
the value of the fileInstallationKey= parameter.
3 Save your changes to the file.
4 Start the installer using the -inputFile option to specify the full path of
your installer properties file as a command-line argument.
For example, on Windows systems, click the Start menu and select the
Run option. In the Run dialog box, enter
setup.exe -inputFile C:tempmy_installer_input.txt
For information about specifying an installer properties file on Linux and
Macintosh systems, see the instructions in the installer properties file
template.
2-60

Running the Uninstall Program Noninteractively
Running the Uninstall Program Noninteractively
Note For information about installing MATLAB noninteractively, see
“Installing Noninteractively (Silent Installation)” on page 2-59.
To run the uninstaller noninteractively, perform these steps:
1 Create an uninstaller properties file.
Make a copy of the uninstaller properties file template, named
uninstaller_input.txt, located in the uninstall folder in your MATLAB
installation folder. For example, on a Windows system, you might execute
this command:
copy matlabrootuninstalluninstaller_input.txt
C:tempmy_uninstall.txt
2 Open your uninstaller properties file using any text editor, and enter
values for all the specified parameters. For example, you can specify the
name of the output log file using the outputFile= parameter. The template
contains detailed descriptions of each parameter with examples.
By default, the uninstaller removes all the products in a particular
MATLAB installation, however, you can specify which products to delete.
In the product list in the template, remove the comment character at the
beginning of the product name. In silent mode, if you specify a product for
deletion that is not one of your installed products, the uninstaller exits and
writes a message to your log file. If you specified mode=automated, the
uninstaller displays the Product Selection dialog box and pauses, waiting
for you to adjust the product selection.
3 Save your changes to the file.
4 Run the uninstaller (uninstall.exe), using the -inputFile flag to specify
the properties file as a command-line argument.
For example, click the Start button and select the Run option. In the Run
dialog box, enter the uninstall command, specifying the full path of the
properties file as a command-line argument:
2-61

uninstall.exe -inputFile C:tempmy_uninstall.txt

Troubleshooting
This topic provides information that can help you solve common problems that
you might encounter installing MathWorks software.
• “Problems During Installation” on page 3-2
• “Problems After Installation” on page 3-6
If you cannot find a description here that matches your problem, check
the MATLAB Release Notes documentation that you received with your
MathWorks products. That document contains the most up-to-date
information available about products and installation procedures. Installation
troubleshooting information is also available at the MathWorks Web site on
the Support page, www.mathworks.com/support/.

Problems During Installation
In this section...
“Installer Does Not Start Automatically” on page 3-2
“Accessing Activation Options” on page 3-2
“Product Dependencies” on page 3-5
Note If the installer appears to become unresponsive (hang), you might want
to turn off any virus-checking software you are running on your system and
restart the installer.
Installer Does Not Start Automatically
The installer should start automatically when you insert the MathWorks
DVD into your DVD drive or when you double-click the installer file you
downloaded from the MathWorks Web site.
If the installer does not start, open a Microsoft Windows Explorer window,
select your DVD drive, and double-click the setup.exe program in the
top-level folder.
Accessing Activation Options
Specifying Proxy Server Connection Settings
If your Internet connection requires a proxy server, you can enter the
server name, port, and password of the proxy server at the beginning of the
installation process or at the beginning of the activation process. MathWorks
supports several types of proxy configurations: Basic authentication and
Digest authentication.
To specify proxy information during installation, click the Connection
Settings button in the first dialog box displayed by the installer. To specify
proxy information during activation, click the Advanced Options button in
the first dialog box displayed by the activation application. (For information
3-2

about Unassociated Activation, see “Activating Without a MathWorks
Account” on page 3-3.)
Enter server name, port, and
other required information.
Click OK.
Activating Without a MathWorks Account
While every user can benefit from having a MathWorks Account, it is possible
to install and run MathWorks software without one. For example, at some
sites, certain users might not be able to create an account for security reasons.
To activate without providing MathWorks Account information, follow this
procedure:
1 Get a File Installation Key for the license you want to install. The
administrator on the license can obtain this key from the MathWorks
License Center.
2 Start the MathWorks installer. Insert the DVD into your DVD drive and
the installer should start automatically.
3-3

3 Troubleshooting
3 You can choose to either the Install using the Internet option or the
Install without using the Internet option. Both paths let you specify
your File Installation Key. For complete instructions, see Chapter 1,
“Standard Installation and Activation Procedures”
4 When the installation is complete and the installer displays the Installation
Complete dialog box, leave the Activate MATLAB option selected and
click Next.
5 In the MathWorks Software Activation dialog box:
• Choose Activate automatically using the Internet. To perform
unassociated activation, you must use the Internet.
• Click Advanced Options. In the Advanced Options dialog box, select
the Activate without associating to a license option and click OK.
Select this option to activate
without an account.
Click OK.
• When you return to the MathWorks Software Activation dialog box,
click Next.
3-4

6 Enter an Activation Key in the Activation Key dialog box and click Next.
Because you are not logged into an account, you must enter an Activation
Key to identify a license.
Note The only activation type available for unassociated activation is
Designated Computer.
7 Click Activate.
Product Dependencies
After clicking Next in the Product Selection dialog box, you might receive a
message telling you that one or more of the products that you selected for
installation have dependencies on other products that were not selected.
To dismiss the message and continue with the installation, click OK. For
a Custom installation, if you want to adjust your product selections, click
Cancel.

3 Troubleshooting
Problems After Installation
After a successful installation, you may encounter problems starting MATLAB
software. Many of these problems originate in the FLEXnet license manager
used by MathWorks products. When a problem occurs, the license manager
displays an error message in a window on your display and also writes the
message to the FLEXnet log file, lmlog.txt, in the matlabrootetc$ARCH
folder. Read the error message carefully; it provides information that can help
solve the problem. For information about viewing the license manager log file,
see “Managing the License Manager” on page 2-54.
For more complete diagnostic information about an error message, go to the
MathWorks Web site, visit the Support page at the MathWorks Web site,
www.mathworks.com/support/. The Support page includes a Search facility
that lets you search the support database for help with an error message
by error number. You can also select the error number from the License
Manager Errors menu.
Select an error.
You can also get information about license manager error messages in the
License Administration Guide, for the FLEXnet Publisher Licensing Toolkit,
available in PDF format in matlabrootetcLicenseAdministration.pdf.
Allowing Access to License Manager Daemons
If you run the license manager on a server that is protected by a security
firewall, you must open the firewall to allow client installations to
communicate with the license manager daemons. For more information about
these daemons, see the License Administration Guide.
3-6

Opening Access to the License Manager Daemon
Using the interface provided by your firewall program, allow access on port
27000 for the license manager daemon. This is the default port used to
communicate with the license manager. If you changed this port number,
specify the port number used at your site. For more information about
specifying the license manager daemon port number, see the License
Administration Guide.
Opening Access to the Vendor Daemon
The port used by the vendor daemon is assigned dynamically. If you need to
open access to the vendor daemon in your firewall, you must assign a port
for vendor daemon communication, rather than using this dynamic port
assignment. You can then open the assigned port number in your firewall.
To specify the vendor daemon port number, edit the License File on your
license server and add the port= syntax to the DAEMON line. For more
information about specifying the vendor daemon port number, see the License
Administration Guide.
Understanding the License Files
A License File is a specially formatted ASCII text file that contains encrypted
product passcodes for each product you are licensed to run. Each product
passcode identifies the number of keys available for that product. The license
manager grants or denies access to a product depending on the availability
of the license keys associated with each product.
The following figure presents a sample License File. Each INCREMENT line
identifies a product, the number of keys available for the product, and other
information. (The INCREMENT lines in your License File might not include
every element shown in the example.) The backslash () character indicates
that the line continues onto the next line.
The lines that begin with a pound sign (#) are comments. The MathWorks
Installer uses the information in these comment lines (license server host ID
or Internet address) when it processes the License File during installation.

License File Search Path
When you start MATLAB, it reads the License File to check for product
licensing. MATLAB searches for the License file in the following locations, in
the specified order. Once it finds a License File, MATLAB stops searching.
1 License File specified on MATLAB startup command line using the -c
argument. You can specify a list of paths to search. When you use the -c
option, you explicitly prohibit the searching of the environment variables.
When using the -c option, keep in mind the following:
• If the path to your License File contains a space, enclose the path name
in quotation marks.
• If you are specifying more than one License File, make sure to enclose
the entire list of License Files in quotation marks.
2 If no License File is specified at the MATLAB command, MATLAB searches
two environment variables, described in the following table. MATLAB
searches the vendor specific environment variable, MLM_LICENSE_FILE first.
3-8

Environment Variable Purpose
MLM_LICENSE_FILE Specifies the location of the License
File, but only for MathWorks products.
(Recommended, because it affects only
MathWorks products.)
LM_LICENSE_FILE Specifies the location of the License File for
all applications using FLEXnet licensing on
this server.
3 If it doesn’t find any License File specified using environment variables,
MATLAB searches the profile folder of the person starting the program.
For licenses that are locked to individual users, the activation application
puts the License File in a folder in your user profile.
4 If it doesn’t find any License File specified in environment variables or in
your user profile, MATLAB checks the licenses folder in your MATLAB
installation for files named license.dat or any file with the extension
.lic.
