Why MATLAB(2010b 64bit) Cannot Find C Compiler?

I am trying to link C compiler to my MATLAB but have been experiencing difficulties.

I have followed the instructions in below thread to install SKD 7.1 and MS Visual C++.

http://www.mathworks.com/matlabcentral/answers/95039-why-does-the-sdk-7-1-installation-fail-with-an-installation-failed-message-on-my-windows-system

The MS VC++ can run C code.(Which indicates that C compiler exists on my desktop). But my MATLAB cannot find any compilers using mex -setup command.

Below is what I got after running mex -setup command --

>> mex -setup
Please choose your compiler for building external interface (MEX) files: 

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

Select a compiler: 

[0] None 

Compiler: 0

    mex: No compiler selected. No action taken.

Select a compiler:

[0] None 

Compiler: 9

The default location for Microsoft Visual C++ 2010 Express compilers is C:\Program Files\Microsoft Visual Studio 10.0, 
but that directory does not exist on this machine.  

Use C:\Program Files\Microsoft Visual Studio 10.0 anyway [y]/n? n
Please enter the location of your compiler: [C:\Program Files\Microsoft Visual Studio 10.0] C:\Program Files (x86)\Microsoft Visual Studio 10.0

Please verify your choices: 

Compiler: Microsoft Visual C++ 2010 Express  
Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0 

Are these correct [y]/n? y

Any help will be much appreciated. Thanks.

You told "mex -setup" where to find your compiler. It said it was done, then gave you a warning about a future change you may need to make to your code (to give you time to prepare for that change.)

So what happened when you tried to build a MEX-file after finishing those steps? Did it work? Did it error? If it threw an error what was the full text of that error?

Hi Steven, Thanks for the quick reply. I did some more research based on your reply, and it seems that I have to modify the directory of "VCPackages" folder in mexopts.bat file. Finally my matlab can compile C file. Thanks again.

[hoho koko]

what are the modifications @Danqing_Lu
