I tried to run this on Windows 7 but it didn't work so I stuck it on my Vista machine. It installed okay, but when I launch it it tells me that it cannot find proper information about what version of the game I'm attempting to run and advises me to run the updater. I tried to do the updater, however, it fails and says I need to be an admin, which I am (tried Run as admin too).

Despite the warning, I'm able to get the menus up but when I attempt to load a module it tells me that it hasn't been installed.

Anyone know how to beat this? I've been wanting to play this for a while now.

Have you tried installing the <span class="podkreslenie">1.69 Critical Rebuild</span>?

Don't bother with the updater, it doesn't work. The post above links to the critical rebuild which is what the game is looking for so that is one possible solution but the GOG version comes fully patched soooo you shouldn't need to do this.

Perhaps first check you have installed it right. Guide to Installing NWN1 for Win7 . If you get it working on one machine then you can simply copy it over to the other and refollow the guide for the settings.

Good Luck :)

Not entirely correct, though advertised and appearing as such.

<span class="podkreslenie">From when I looked into the issue</span>:

Missing:
xp1patch.bif (7.69MB): I'm not sure this file is used anymore. The 1.69 linux server patch specifically instructs you to delete this file.

Incorrect File Size/Date:
xp2patch.bif (127,609kb): Critical rebuild patches this file to a 359,896kb file that was modified 3 years after the GOG install file (4/29/2005 vs. 5/15/2008)
xp3.bif (463,718kb): Critical rebuild patches this file to a 627,919kb file that was modified 9 hours before the GOG install file (5/15/2008 10:46PM vs. 1:46PM). Weird.

Given the above file sizes, there's your missing ~0.4GB

The culminations of these discrepancies are that users will be missing some textures (partially invisible icons, unexpected silver textures, etc.) and quite possibly game data, but I was able to successfully join a multiplayer server with only the above mentioned texture issues. We have had reports of players with the GOG install crashing on some of the newer tilesets however (Steamworks), so that is likely something missing from the game files. With our automatic updater having a force install option for the Critical Rebuild, these issues were resolved once the patch was re-applied.

Thank you for the correction :)
