just remember that Microsoft got the new kid to organise the damn registry. stuff in their is all over the place. you havent deleted the Bioware key unless you used edit-> find, and even then you should go through for black isle, baldur gate, infinity etc.

i woudnt think a file would cause it - the install for BG is actually pretty neat. i havent seen any files stuck in the wrong place.

you might be able to run the install program directly and bypass the aluncher. the BG cd is in my bros cd is in his machine which is off so i cant check, but itd be called setup and be on CD1. it might work, it might give an error.
