Works fine for me on windows vista.

I'm going to have to stop being lazy and just install it, BRB : O

This is the original right?
Because the second one was god awful.

I have the Neverwinter Nights Deluxe Edition here, even so the box says its Windows7 and Vista compatible, so far I haven't managed to make it work on Windows Vista. When trying to start the thing, it launches a process background (nwnmain.exe) and then doesn't do anything. Updating to 1.6.9 didn't help either. The tools do seem to work, just not the main game.
 
Game seems to runs fine in Linux under Wine and on an old Windows98 machine.

Can't remember whether I ever tried NWN with Vista. I'm gathering everybody's tried running in compatibility mode as admin?

I had no issues except for a friend not being able to go online for some reason.

Works with Windows 7 32 bit for me. Might need to give it Admin permission to run it.

I can't get the NWN toolset to work with Vista, but I'm pretty sure the game itself ran fine.

I've played NWN on XP, Vista and 7 and so far I've had no problems, so it should work just fine for you, I think :)

I can play NWN Diamond on Windows 7 x64, BUT it's not made well for multi core processors so I can't get many frames on it :(
