MEX compilator not found

HI .I use Matlab 2010a and I would like to generate compilated code I have installed Microsoft SDK 7.1 Microsoft visual studio 10.0 Microsoft visual studio 10.0 SP1

I have an environmental variable matlab set to the matlab root directory and one MSSDK variable set to: C:\Program Files (x86)\Microsoft Visual Studio 10.0\SDK

but I can't find the compilator when I type mex -setup

Could you explain to me where the mex -setup looks for different compilators and how I could make him see this compilator

One possible issue is you are mixing 32 bit MATLAB with 64 bit compilers or vice versa. Did you check that?
