How can i install c compiler on 64 bit computer to run stateflow

I have Matlab R2010a. When I run a stateflow chart it gives me an error of missing c compiler. Suggestions on the internet says to run mex -setup in the command line.I did that. But I am getting the following error. Can any one please suggest a step-by-step procedure to run stateflow on my R2010a matlab.

>> 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.

You need to install a compiler which R2010a supports. A list of supported compiler can be found here. After you have done that run mex -setup again to select it and you are good to go.
