Display Issues NWN Windows7

I am on the brink of extreme depression here with an issue I am having trying to play my fav pc game NeverwinterNights1. I just recently upgraded to Win7 from XP and when I try to play NWN the display flickers with lines running across the screen. It ran perfect on the PC with XP. I have done a clean install, tried running as admin, the whole nine yards but to no avail. Went to the BioWare site looking for answers but nothing posted there helped at all. Anyone have any ideas for me? I would greatly appreciate any help at all!

 

Had a quick look and came across this.

I have a few older games that wont run properly on Win7 and it appears from the few articles I just looked over that NWN has/had an issue with Vista/Win7 UAC.

Now bare in mind I have in no way tested this, it's just a Google search backed with experience with other older games and Win7.

 

I can't speak for win 7, but NWN1 was one of my favs too. I can't run it on my vista ultimate 64. Luckily, I've got a backup plan. Break out the trusty ol' 1.8 P4, w/ a radeon 9800 AGP card. Yeah Baby!!! :cool
This ins't the only reason I keep it around, I can't do any of my ....... Custom Firware, or Emulators on PSP's, or 360 on this darn Vista. :cry Not sure if you even have a copy of win xp or anything, but you could always try a dual boot option. I did it for years,.... (mutterrr) til I did something stupid, and had to resort back to 2 OS' Vista ultimate and Linux. My fav NWN was the Diamond edition, the one that came with the undermountain series. :cool

 

I remember pulling my hair out over this one... I wish I remember how I fixed it.

You say you tried running it as admin? Try messing with the compatibility settings as well. Right-click the main exe, go to the compatibility tab, and set it to run in compatibility mode for Windos XP SP 2. Then check the boxes to disable visual themes and desktop composition, and try run the game again.

EDIT:
If everything else fails, the Diamond Edition from GOG.com runs perfectly fine in 7. I think that might have been how I fixed it in the end.
