There are already two threads about this topic in the main Neverwinter Nights board, and neither have been addressed, so I'm posting it here.

When running the "Premium Modules Re-installer", the progress indicator message will get to "Game version 1.66 or higher", and then crash to "Program has stopped working".

Windows 7 x64.

Well, no. Nothing has been suggested in either of the other threads. That's kinda why I said "neither have been addressed".

Anyway, doing what you said works.

Not really. I mean, there are a couple games where Compatibility Mode is well known to be a staple, like Quake IV (you can't even run the Autorun splash unless it's set to XP compatibility mode. That even applies to the bonus content disc. Go figure.), and then there are games where you actually have to run VIrtual XP Mode to run them, like The Bard's Tale (2004). Since the v1.69 patch was released in July 2008, I kinda thought Vista/7 compatibility would have been applied already.
