I am using Parallels 11 on my IMac which has a Windows XP and Windows 7 VM. I checked my system and I have 64 bit Windows 7. I tried to upgrade Windows 7 to Windows 10. After downloading and running the download tool for the 64 bit installation, Windows XP opens and I get an error that the 64-bit version is not the correct version. I do not want to upgrade Windows XP. How can I use the wizard to upgrade the Windows 7 VM?
