Yeah it's ancient but System Shock 2 is a great game (as was the original). I tried re-installing it and got the "DX6.1 Limitation" alert. Install aborted. The weird thing is that I tried running the game within Windows 7 64 bit from my previous XP Pro installation (my XP disk is still connected) and the game started and ran at least through the start of a New Game. Moved around a bit, basic controls seemed fine. But there was no sound. I tried the Speaker Test from the control panel and got nothing. I actually did a wholesale copy of the SS2 directory from my XP disk to my 7 disk and the program ran again, but still no sound.
Anybody have any ideas on how to get this to work? If I install DX 9.0c March 2009 will that recover the DX6.1 capabilities I need?
