Hi Guys
I have manged to get Kotor 2 working with vista.
Heres the back story (every1 loves a story) After installing the full game and then updating the game to 1.0b (manually not using the update option in game menu) i fired up the game, after a few seconds i get a window stating the game is not working and get the option to close it down thats it. After 'right click>Properties then compatibility tab i set it to run as windows XP and run as Admin but no luck i got the same window.
After that failed i unchecked the run as windows XP compatibilty mode and i checked the following in the Compatibility Tab:
Disable visual themes,
Disable desktop compostion,
Disable display scaling on high DPI settings
After checking all of those i started the game and it worked fine. The reason i think this works is 1 of the above settings (Visual Themes I think) disables Aero in Vista and i think that cuses alot of problems in games. Bottom line is i do the above action with every game i play and i rarely get any probs with them in vista.
Also to note on my config check all my components are green except my graphics which fails (red icon) due to the program thinking i have out of date drivers but i'm playing it on a GeForce Go 7900 GS.
Hope this helps.
