compiling for 32-bit from win64 OS

I need a way to compile -- on a machine running win64 OS -- both mex files and MATLAB standalone applications for a 32-bit target machine.

Is there a way, within 64-bit MATLAB to set mex and deploytool to compile for a 32-bit target?

Failing that, can I install both 64-bit MATLAB and 32-bit MATLAB on the same machine (running win64 OS) and use 32-bit MATLAB when I need to compile for a 32-bit target? I've been told that 32-bit and 64-bit may not be able to safely co-exist on the same win64 platform. Is there truth to that?

FYI, I run both for 5 years without any problem.

===========

Really? I've been told that a 32-bit installation and a 64-bit installation may try to use common files in a common location or something, and may end up repeatedly overwriting each other.

FYI - I confirmed with Tech Support that 64 bit and 32 bit MATLAB can co-exist. They also mentioned the -win32 flag the DEPLOYTOOL documentation:


-win32 Run in 32-Bit Mode
Use this option to build a 32-bit application on a 64-bit system only when the following are both true:

*You use the same MATLAB installation root (install_root) for both 32-bit and 64-bit versions of MATLAB.

*You are running from a Windows command line (not a MATLAB command line).
