Calaethis: Missing files making fixpacks/mods not want to install generally mean that your BG1 CDs are scratched so files weren't copied in the Tutu conversion. What is a good idea to do is look in this thread and see if your install is missing any of these files:

If so, it means that they were corrupted on your BG1 install so you should copy them over from the CD. [img]smile.gif[/img] Then stuff should install properly, and I'd recommend you use the Tutu Fixpack at least.
