Hello all,

Had a bit of trouble firing up NWN2, solution may be found below if the page is working:


If not, I'll outline the solution as follows. The problem is related to the pre-Vista hardware detection packaged with the game. First of all, go to C:\Windows\System32 or C:\Windows\SysWOW64 if you're using Windows 64. Locate dxdiagn.dll and take ownership - right click, properties, security tab, advanced, owner tab, click edit and add yourself as the current owner. Rename this .dll as something like dxdiagn.original and paste this .dll in its place:


This should solve the issue, at least it did for me. This issue shouldn't happen if you're on a newer build of Windows 7, though you can never be sure!

Just stop using Win7 RC. RTM works fine out of the box.
