Do you have Tweak UI? If you do, run it from the Control Panel and under the Repair tab use "Repair Reg Edit" (You can get Tweak UI from Microsoft) Also, if in doubt, after you uninstall, go to regedit and search for "poser", "curious labs", "metacreations", etc and delete those references before you reinstall. Be warned, tho- playing with the registry is a fools errand and I won't be held responsible for your having to completely reinstall windows!!! ;-)
