MATLAB: Mex compiler setup for Simulink StateFlow

mex compilerstateflow

Hello.
I'm trying to use Simulink StateFlow.
But there is problem of compiler.
I setup the compiler using:
>> 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? y
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
*************************************************************************** 
  Warning: MEX-files generated using Microsoft Visual C++ 2012 require 
           that Microsoft Visual Studio 2012 run-time libraries be  
           available on the computer they are run on. 
           If you plan to redistribute your MEX-files to other MATLAB 
           users, be sure that they have the run-time libraries.

  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  
           Building with the -largeArrayDims option enables the new API. 
**************************************************************************
However, when I run the StateFlow model I made, the error message appears.
"Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks.
Use 'mex -setup' to select a supported C-compiler."
How can I solve this problem?
I also tried to install Microsoft SDK 7.1 to use this compiler.
However, I failed installing SDK 7.1. I don't know the reason.

I don't know if this will work, but try booting MATLAB in administrator mode (right click and select run as administrator) then repeat the mex -setup...
