Hello,

I wrote a MATLAB code that uses mex-file with a computer that uses windows 32bits, and this code worked. Then, I imported this code on an other computer that uses windows 64bits (I'm still building this code with Microsoft Windows SDK 7.1 - C++) and I have the following error: C:\users\documents\matlab\StdAfx.h(19): fatal error C1083: Cannot open include file: 'Afx.h': No such file or directory

I made some researches about my issues, and I think it could be a compatibility error, but I cannot find how to solve it, do you have any idea?

Comment out the #include stdafx.h line. It is an optimization for some microsoft compilers, so at worst your program will compile more slowly.
