KOTOR2 Gaming issues on Win Vista 64bit

Ok, so I've been driven demented since I bought this game. It was pain enough that it took me 4 CD's to install the game, but when I installed it, the game ran once before it decided not to work again. The error I kept getting was that it needed some NVidia Detonator drivers 45.23 before it would work. Now I searched the web and tried to find these drivers for Vista 64bit. I eventually found it, downloaded it and installed it. Tried to run the game again, still no work. I updated my drivers for my graphics card. Still no luck getting the game to run. I can't even update the game at the moment as it tells me it can't find the update file.

So in the normal fashion, I decided GIYF (google is your friend), I googled the error I was getting and I came across some official Star Wars: Knights of the Old Republic 2 forums. Their first recommendation which helped to find the core of the problem, is to turn off sound in the configure menu. The game can now be played without problems, however without sounds. Playing the game without sound is unnacceptable though. I actually found out the issue is actually with the file mss32.dll. This is the Miles sound driver that is used in the game. The forums recommended downloading another version of this file. Unfortunately, their links were dead and I only found one arhaic version of this file which made no difference at all. So assuming that the game is using the same driver as it's predecessor, KOTOR1, I decided to try something mad. Now I've just recently finished the first game, so I still have it installed. I decided to copy the mss32.dll file from the KOTOR directory into the SWKOTOR2 directory. Tried to launch the game again and lo and behold it works without a problem. I've now progressed a fair amount in the game without seeing any problems.

What I don't understand is, that the version of mss32.dll for KOTOR2 is 6.6.7.0 and the one I replaced it with is 3.0.0.0. In my thinking, I would assume this would not work, however, I was wrong. So anyone having a problem with KOTOR2, try the older version of mss32.dll, it's much better than playing the game without sound.
