I just beat this a while ago on W7 32bit via Steam.
I got it when it was like $3 a few weeks ago.
It runs perfect, except when I put grass on.
Sometimes the grass would go crazy and fill the whole screen, so turned that off.
Also, some of the visions and other random videos only showed sound, no video.
Of course, I was running it on an external hdd(only have 128gb ssd), so that could be why.
I beat it as evil focusing on force powers, but might do it again as good with more of a melee focus.
