A demo version of the MATLAB Compiler 3.0 (R13) limits users such that they are not allowed to distribute their compiled stand-alone application. The full version of the MATLAB Compiler is necessary in order to distribute your compiled application to others.
There are two ways in which the demo version of the MATLAB Compiler differs from the full version:
First, the MGLINSTALLER, which normally resides in the following directory, does not exist in the Demo version of the MATLAB Compiler and Libraries:
$MATLAB/extern/lib/win32 (where $MATLAB is the root MATLAB directory)
The MGLINSTALLER is needed to distribute stand-alone applications to users who do not own MATLAB. This is not necessary in the demo version of the MATLAB Compiler because applications created with the demo version cannot be distributed.
Second, stand-alone applications created with the demo version of the MATLAB Compiler require a license file before they will run. This license file should be located in your $MATLAB\bin\win32 directory. That directory must be on the system path before any other installation of MATLAB.
If you install the stand-alone application on a system that does not have MATLAB, you will receive an error such as:
Could not check out a license for CPP_Math_Library
or
License Checkout Failed...
With the full version of the MATLAB Compiler, the generated executable does not check for any licenses. This is only used to prevent distribution of applications created using the demo version of the MATLAB Compiler.
