Some people are able to get it going on Vista. I haven't tried it on mine yet, but every other game I've loaded on has worked without any problems. See this thread
for problem-solving playing Kotor and TSL on Vista. If you are having problems
running the game in Vista please post those issues there. I may merge this thread with that one, also, if this turns into a more problem-solving thread so that we can have everything in one place.
When I install a game designed for xp, I'll right-click on the shortcut--properties--compatibility and check both 'run this program as administrator' and 'run this program in compatibility mode for' and chose xp sp2. There's a service pack 1 coming out for Vista around Jan '08 (I believe) and hopefully that will resolve some issues (and not make more.
). Bioware has a Kotor self-help section here
but you may need to register as a member (along with registering your game) to post in it.
