I have a mixed 32/64 bit installer. I've tested it on my 64-bit system and it looks good. Is there some way to make it install as if it were on a 32-bit machine so I can verify that the correct files are being installed?
In order to test the 32-bit installer from the mixed package you can only install it on a 32-bit real or virtual machine. It cannot be tested on a 64-bit machine.
