Error Mex -setup and Matlab 2011a

I am trying to compile some c++ code into a MEX in MATLAB 2011a under Windows 8 64 bit. I get the following error:

Error: Could not find the compiler “cl” on the DOS path.
Use mex -setup to configure your environment properly.

C:\PROGRA~1\MATLAB\R2010A\BIN\MEX.PL: Error: Unable to locate compiler.
