Upgrade advisor for Vista tests software for 32bit or 64bit

[klmorrill]

Running vista upgrade advisor on a machine running XP Pro. Old P4 32 bit machine. When it test your software and its conclusion is your sofware is ok for Vista. I'm assuming that for a 32 bit machine not a 64 bit machine.

Are my assumptions correct?

It is for 32-bit versions.
But if you have a 64-bit cpu you can run the 64-bit version of Vista. It is important to make sure you can obtain all the 64-bit drivers for your hardware that vista may not automatically install during setup and Windows update. (i.e., Video driver, and sata/raid driver-vista will install audio drivers, but these may not work well resulting in failure to mute speakers if using headphones)

P4 appears to support EM64T support for 64-bit
