After a successful installation, you may encounter problems starting MATLAB® software.
Many problems starting MATLAB software after an installation
originate with 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
Read the error message carefully; it provides information that can
help solve the problem. For information about viewing the license
manager log file, see Manage the License Manager.
For diagnostic information about a particular error message:
Visit the Installation Help support page at the MathWorks website, www.mathworks.com/support/install.
Search for the error message.
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
If you run the license manager on a server that is protected by a security firewall, 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.
Using the interface provided by your firewall program, allow access on port 27000 for the license manager daemon. This port 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.
The port used by the vendor daemon is assigned dynamically. If you need to open access to the vendor daemon in your firewall,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
DAEMON line. For more information about
specifying the vendor daemon port number, see the License Administration
