I would like to use the Microsoft Windows SDK 7.1 as my C compiler in MATLAB 7.14 (R2012a) on 64-bit Windows.

I have already installed the Microsoft Windows SDK 7.1, but MEX still cannot find a C compiler. How can I correct this?

This may be due to a Microsoft issue where the SDK 7.1 compilers are missing. Try the following:

1. Go to the solution 1-G1P8HP titled

 Why do I get errors with compiling even after I have installed the supported compilers Microsoft Visual Studio 2010 Express and Windows SDK 7.1?

at the bottom and follow the instructions there to apply the Microsoft SDK 7.1 patch.

2. If the above did not work, uninstall SDK 7.1. Then reinstall SDK 7.1 following the directions specified in solution 1-FPLDGV titled

How do I install Microsoft Windows SDK 7.1?

at the bottom.

This issue comes up for R2014a as well and this update, applied after SDK 7.1 is installed, solved the issue. http://www.microsoft.com/en-us/download/confirmation.aspx?id=4422
