Why do I receive a License Manager Error -103 when running MATLAB 6.5 (R13) on Windows Vista or newer?

The latest version of Windows that MATLAB R13 officially supports is Windows XP. Running on anything newer is considered unqualified and there is no MathWorks approved fix to this error at the moment.

For more information about the system requirements for MATLAB, see the R13 system requirements here:
