My parents have VMware Fusion 1.1.1 and whenever I upgraded their iMac to Snow Leopard, the 1.1.1 did not work. I did some digging and found out that 1.1.1 is not compatible with Snow Leopard. So we ordered Fusion 3. Question is, when you upgrade does it uninstall windows? Or does it just "upgrade" the app? Also, if it does uninstall windows, how do we back up the files if we can't boot into windows? Please help me! This is really important to my fathers business!
