I have been using Matlab 7.1 with Microsoft Visual Studio on a 32 bit Windows 2003 server. Now, I'm trying to move all my applications to a 64 bit 2008 server. I installed Matlab 7.7 along with Visual C++ 2005 since this link suggests that these versions are compatible - https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2008b_SupportedCompilers.pdf.
When I type "mbuild -setup" in 64 bit Matlab 7.7, it does not detect any compilers. When I type the same command in my 32 bit Matlab 7.1, it detects two compilers - Microsoft Visual Studio and the Lcc compiler in Matlab folder.
Do I need to do something else to make this system work in 64 bit?

Most possible reason for this behavior is that the PATH is not set for the new compiler or it is added behind a 32-bit compiler. After installing a compatible 64-bit compiler in the target machine, it has to be set in the PATH system environmental variable in order to be picked up by MATLAB. MATLAB picks up the first compiler in the PATH, so make sure it is added on top of the list of paths in PATH.

I installed SDK 7.1 and put its location in the PATH environment variable. Matlab still fails to detect it as a compiler. Do I need to add another Matlab specific env variable? Seems like MSVCDIR is only needed for certain versions of Visual C++. Do I need to register that installation somewhere?
