Thanks, guys!
>>You can find 2.0.3 here

  It seems to want the exact 2.0.0 version.
What happens is this: I start the traitors gate setup, it begins, then tells me: "The following sofware is required but was not found on your computer: Quicktime 2.0. Setup may not function properly."
  I tried going ahead anyway, and it installs 2.12 and 3.02 fine, but trying to run the game afterwords just shows a black screen then exits.
  And the 2.12 I have is 32bit, same as my windows version(xp SP3 32bit).
   I've tried the usual kinds of configuration shuffling
