Problem with mex compiler

Hi there,

I had this setup in the past and it worked well. But after upgrading to R2012a I can't run the mex compiler. At the setup, the following error is received... Any advice is welcome!

>> 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/R2012a/win64.html

Please choose your compiler for building MEX-files:

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

Select a compiler: [1] Microsoft Visual C++ 2008 SP1 in c:\Program Files (x86)\Microsoft Visual Studio 9.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Visual C++ 2008 SP1 Location: c:\Program Files (x86)\Microsoft Visual Studio 9.0

Are these correct [y]/n? y

according to the error message, it would be helpful to check this and explain it accordingly:

This may indicate that the "X64 Compilers and Tools" or the Microsoft Windows Software Development Kit (SDK) is not installed.

There have been problems with the order of the installations and a bugfix from Microsoft. Please search in this forum for the many corresponding threads.
