I seem to be having trouble installing Hog4 2.1.0 on Windows 7. I previously has 1.0.0 installed, when I attempted to upgrade I got almost all the way through the install, and when it got to the fixture library the install aborted and uninstalled everything. Now I can't install any version of Ho4 PC on this computer.
BTW No antivirus software, and UAC is turned off. I am logged in as the administrator.
