Just thought I'd start a separate topic considering all the other Vista-related problems. I'm testing Vista SP1 RC as one of the Microsoft Beta testers and BIA:EIB now installs perfectly! Hopefully it'll be released before XP SP3 (yes, its out in Beta too :-))
Edit: Although it now installs o.k., there are still compatibility issues unresolved. Runnimg it in compatibility mode doesn't help.

Further info, Vista reports a compatibility error with "Starforce Protection" which is a copy prevention app. Their website gives you info on updating for Vista but it when you d/l the program, it somehow can't find the outdated version within the "System" folder of the game.
