I have a Power Mac G3, as a secondary computer, which was initially set up to work with an earlly version of Virtual PC -- 2.1, along with 8.5 system software, which I subsequently updated to 8.6 to correct a software glitch. Later on, I installed System 9.0, unaware that it was incompatible with Virtual PC 2.1, and ever since I have not been able to access the Virtual PC end of the machine. (When you do a search, the Virtual program is listed, but you can't get to it.) When I tried to use the OS 8.5 disk as a start-up disk in order to reinstall the previous software, I received a message that the computer, installed with 9.0 would not work with it. Is it possible to remove Mac OS 9.0, and then reinstall the 8.5, in order to be able to retrieve Virtual PC 2.1? If I decide to get an updated version of Virtual PC, which I realize is now a Microsoft product, rather than Connectix, would it be possible to install it over the old version and then my previous work on Virtual PC--all files and folders-- would reappear? Any input regarding this "locked up Virtual PC on a PowerMac" problem would be greatly appreciated, including mention of any other forums that might be able to address the question.
