Sourceforge doesn't seem to have it, and neither does my yum repository (I didn't change anything there, so I think it's still the official Fedora Extras). I'm looking at other repositories' lists where they have them on the web, and I can't find it.

EDIT: alternately, is there a way for me to do manually whatever winesetuptk would do automatically? And is this possibly complicated by the fact that my CD drive is USB?

So far my problem sounds exactly like the problem that other people have had running Blizzard games under Wine, and winesetuptk was apparently what fixed it for them.
