My Parallels 5 stopped working. When I tried to load it and then start Windows 7 it would go to a blank screen. Most recently I would get a message that a driver was missing. So I uninstalled 5 and started the installation again. It got an update to the program but when it checked my system to see if it could install I got the message "Parallels Desktop cannot be installed on your Mac....Parallels Desktop can be installed only on Mac OS X Leopard (version 10.5.2 or higher) or Mac OS X Tiger (version 10.4.11 or higher)." Well, I have OS 10.7.5 so why do I get this message? Would going to a later version of Parallels help?
