Why do I receive MathWorks Licensing Error 37?

Why do I receive the following error:

MathWorks Licensing Error 37. A licensing error occurred while trying to use <PRODUCTNAME>.

This error is an indication that the port number on your SERVER line in your license.dat file does not match the port number on the SERVER line of the license.dat file on the server. This can happen if you have two versions of FLEXlm running for two different versions of MATLAB.

The license.dat file located on the server machine is located in:

Windows

---------

$MATLAB\flexlm

Linux/Unix/Mac

------------------

$MATLAB/etc

(where $MATLAB is the MATLAB installation directory)

The license file on the client machine varies depending upon operating system and version. For R2008a and above, the license file is generally called network.lic and is located in $MATLAB\licenses (where $MATLAB is the MATLAB installation directory). For versions prior to R2008a, the license file will generally be the following:

Windows

---------

$MATLAB\bin\win32 (for 32-bit MATLAB)
$MATLAB\bin\win64 (for 64-bit MATLAB)

Linux/Unix/Mac

------------------

$MATLAB/etc

(where $MATLAB is the MATLAB installation directory)

That is not relevant to this Question.
