Right, but the problem is that it a) overwrites the original files and b) installs "backups" of the original files, but they're actually installed with the patch, not backed up from the originals. I want the original SDK files--not the UP versions. And I want them from Firaxis--not the UP installer. Yes, I could trust that grumbler packaged virgin copies of the SDK files to be installed as backups, and for myself I'd be happy to. Since I'm going to ship this software as part of BUG for others to use (and trust), I want to make absolutely sure I get them from Firaxis.
