    Invalid MEX-file
    'C:\ILOG\CPLEX_Studio_Preview122\cplex\matlab\x64_win64\cplexlink122.mexw64':
    This application has failed to start because the application configuration
    is incorrect. Reinstalling the application may fix this problem.

    My Cplex version:12.2
    My matlab version: 7.9.0
    My OS :Microsoft Windows Server 2003 Enterprise x64 Edition Service Pack 2
    (I also try in another PC which is Vista Premium x64bit, the same error appears)

    Please lend a help, thanks.

    >>addpath C:\ILOG\CPLEX_Studio_Preview122\cplex\matlab\x64_win64
    >>savepath

    and if you want to run cplex examples, you need to add the path of examples to matlab's path by addpath

    >>addpath C:\ILOG\CPLEX_Studio_Preview122\cplex\examples\src\matlab
    >>savepath

    Please tell me if you still have problems.
