I'm running Panther 1.3.6. I installed a copy of virtual PC I borrowed and it didn't run. Now I'm trying to install a different copy but it won't install. I think it's because there're still traces of the old copy, like when a trial expires and you try to install it again but it won't run. Is there something in Panther that's like the Windows registry, where I can go in and erase all traces that this software was previously installed? Thanks.
