The game needs native dxdiagn.dll to work around either bug #20609 or bug

wbemprox: Don't fail if there are less objects than asked for in
IEnumWbemClassObject::Next.

Reverting the patch on wine-1.5.24-119-g209b58c makes the crash go away.

No demo version has been released. Let me know if you need further logs or
tests.
Tested with Neverwinter Nights 2 v1.23 (build 1765).
