It says that you can select which components you want when you run EoU, but that's not happening for me. Any suggestions?

Hmm, you unzipped it into the BG2 directory .. clicked the .exe file and a little window popped up ?

If so .. you get a few options .. language first I think.

After that it asks you to automatically install everything or let you choose per component. I think that's where you went wrong .. if not .. I dont get it :D

Oh, Ask About Each One, ok, got ya, thanks.
