I haven't yet... I cant open the program at all this time... heres the story its ...complicated I originally installed parallels no problem and windows xp as well... but I have a seizure disorder since I was 15 and during one my computer dropped and screwed everything up... my system got corrupted and I had to reload it... and parallels as well.. so I deleted everything via a search for parallels and I think xp was in the folder somewhere because I tried windows xp and nothing that is actually the xp itself... so I assume It was deleted... I also installed parallels originally before I upgraded the system to 10.5.2 from 10.5.1 this is a mac mini... do I need anything extra?? it was working mostly with the new system after the upgrade except it ran....and while using it it would rarely but stiil sometimes quit out... but most of the time worked fine...
