How to help Stateflow locate the C-compiler?

When I try to run any model in which Stateflow components are used, I get the following error:

"Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler."

Even after running 'mex -setup' as suggested in the error message and choosing the compiler, the error persists!

Any idea how to help Stateflow locate the C-compiler?

If you are having problems after running mex -setup, then the path to the C compiler is incorrect, thus it cannot find the C compiler in question. Check your environment variables for the C compiler and make sure that the C compiler is in the folder where Mex -setup is stating.

I didn't get what u mean by "Check your environment variables for the C compiler", how to do that?

I checked the folder stated by mex-setup, the C compiler is there.

If that's of any help, when I run mex -setup I am getting the following:

>> mex -setup

Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2013a/win64.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n?

Select a compiler:

[1] Microsoft Visual C++ 2012 in C:\Program Files (x86)\Microsoft Visual Studio 11.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Visual C++ 2012

Location: C:\Program Files (x86)\Microsoft Visual Studio 11.0

Are these correct [y]/n? y

Since you are using Microsoft Visual C++ 2012 in R2013a, you might be affected by Bug #931218. Please see if installing the patch fixes the issue.
