Re: KOTOR 2 VISTA FIX(worked for me)
 

service pack 3 is for 64x media users only, it allows for direct x 10 installation.
why doesnt that driver work? because it isnt signed. microsoft is currently charging for digital signitures of drivers, no digital signiture, it trips DEP, which in some cases, cannot be turned off. is there a way around this? well using the digitally signed driver from the first KOTOR is a novel solution to a complicated problem, there is a way to register drivers manually with msconfig. if anyone knows the command line to do this, PLEASE SHARE!

also. this game uses wav files. if youre a geek you know the inherent dillemma between vistas sound drivers and wav files. creative alchemy(tm) might not be a bad idea.

the vista command(as in command line; accessories CMD.exe) to disable driver checks is bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

this hasnt worked for me, perhaps it will help some of you

more options:
press f8 @ boot DMI pool entry(before the windows scroll, after the motherboard spiel), then scroll down to disable signature checks.

a program called "readydriver plus 1.1" that didnt work at all for me

what worked with all programs on my particular system (quad core intel core 2 duo, 4 gigs of ram, 2.8 gb video vista ultimate 64x with dep hardware features) was to download both SDK and .net 3.0 and use the command line bcdedit.exe /set TESTSIGNING ON

this left me with some watermarks on the edges of my screen, which are fully obfuscatable, and remarkably tiny.
