I know this has been answered, but Yes - it uses Windows on Windows and as stated, as long as it isn't a 16-bit installer, you should be good to go.
I've never had an issue running various 32 bit apps inside of my 64 bit environments
Ok I'll get the 64-bit version then.
good choice it can recognize allot more RAM than x32
Say that the RAM is the same number, is there a performance difference between 32-bit and 64-bit?
there can be on some very intensive programs... that are written specifically for x64 (the latest photoshop is an example) there are improvements w/ x64 over x32 but you need 64-bit drivers and hardware.
64-bit OS also has better security than 32-bit
Why does Focus Magic, yes I know its a 32-bit app, not install and run on Windows 7 64-bit Home Premium?
its installer may be 16-bit or... some programs are just written 'poorly' (for a lack of a better term) and just can't run on that architecture. I know people have issues installing the Focus Magic Photoshop CS4 plugin on x64 machines
