I'm using relase 2016b and i'm trying to change the default c++ compiler. When i type mex -setup i get the following:

 MEX configured to use 'Microsoft Windows SDK 7.1 (C)' for C language compilation.
 Warning: The MATLAB C and Fortran API has changed to support MATLAB
   variables with more than 2^32-1 elements. In the near future
   you will be required to update your code to utilize the
   new API. You can find more information about this at:
   http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.
 To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

Then i type mex -setup C++ and i get the following:

 MEX configured to use 'Microsoft Windows SDK 7.1 (C++)' for C++ language compilation.
 Warning: The MATLAB C and Fortran API has changed to support MATLAB
   variables with more than 2^32-1 elements. In the near future
   you will be required to update your code to utilize the
   new API. You can find more information about this at:

At the end i'm not able to configure anything

This generally means you don't have another supported compiler installed. Each release has its own list, and some compilers don't work on some OSes.

Hi, how can i default back to the original compiler? I ran mex -setup C++ to install MatConvNet, but now i want to remove it, and return back to the default API, how can i do that?
