Just to be a little more specific, I get the impression from my notes and the post I saw a few days ago (maybe I’ll try to find it) the three files need to be moved to where they belong, first. Second, install MoW using the exe.
I don’t know. Maybe it would work just moving the three files over as well as all of the already decompressed files.
I’ve kicked around making a fresh NWN2 install using my original 10 CD version, patching it up using the original patches, installing each individual expansion (MotB/SoZ) and patching, then installing MoW and patching. I’ll do it when I can afford losing three hours of my life.
PS: My biggest score was buying several copies of NWN2 Platinum on Steam for $4.99 each during a holiday sale. Of course, those versions didn’t have MoW. They did lead to years of playing mp, though.
As a side note, years ago I gifted one of the Steam copies I bought to a very prominent NWN1/NWN2 community member (simply to make it an easier re-install for him when we were starting another mp game). What great times we, his wife, and buddies had.
Sadly, he passed away three months ago, at a young age.
