Seems that people are getting it to work on win7. I tried the the xp type of install and the win7 type of install, but neither work. Usually after reboot my computer stops on the first screen. After the 30th restore from a backup of VISTA SP2, I am about to give up on EWF for VISTA. Maybe I am supposed to install EWF before the SP2, I am clueless at this point.
