I am using Vista... hmm.
My game WAS installed in the Program Files diectory and my Active User Control WAS on, but not anymore. I re-installed the game again directly on C:/ganes, and disabled my Active User Control (btw. thanks for the tip on the last one. That function has bothered me ever since I bought the computer), so if that would ever become a problem in the FUTURE it wount now.
Yet still, *sight* same old problem still occurs :-(
I had exactly the same problem of yours. I tried several times of uninstall, reinstall, restore of both BG1 and BG2 but still failed. Finally I move BG1 to the preset folder as BGT indicated (which is C:\program files\black isle\baldur's gate), and the problem was solved!!
Hope this can help you.
