I tried to script a custom installer that will detect the correct location to install FfH. I wrapped the Assimilation mod with it. If you guys could download and install assimilation it should: 1. Install Assimilation in the correct locations. 2. Place a shortcut on your desktop that runs Assimilation. Download: http://forums.civfanatics.com/downloads.php?do=file&id=9911 I especially need people to try it with unusual install options (Steam, BtS installed on your D drive, foreign installs, Civ4 complete installs, etc). Thanks guys, let me know if it works for you. If it does I can start adding some prereq checks to the installer so we can pop an error and warn players who don't have bts 3.17 and such installed and try to avoid those initial errors that stop a lot of people from trying the mod.
