MATLAB Could not find the compiler “cl” on the DOS path

Question

I'm using Matlab 2009b 64bit and I installed Microsoft Visual Studio 2008 Express for compiler (but it just installs in 32 bit in C:\Program Files (x86)\Microsoft Visual Studio 9.0\Microsoft Visual C++ 2008 Express Edition with SP1 - ENU). Then I mex a file in Matlab, it has error:

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

...MATLAB\BIN\MEX.PL: Error: Unable to locate compiler.

Anyone have this problem? Share your experiment to solve it. Thank you!

Why do you use such an old version of Matlab? What is your Windows version? — Woeitg

Finally, I solved this problem. The key is compiler 32bit(ex Microsoft Visual Studio 2008 Express) is not compatibility with Matlab 64bit. So, I remove Matlab 64bit and then install Matlab 32bit to solve this problem. This work awesome.
