I had been running Parallels 13 for some time when I decided to give version 14 a trial. I downloaded the dmg file and installed it, but found there was little if any new functionality that I found necessary and so decided to go back to 13, at least for a while. I removed the version 14 desktop and Toolbox apps, downloaded the version 13 dmg file from my account and installed it, but when I tried to run it and specified the Windows pvm file I got an error telling me: The path you have specified contains the files that belong to another virtual machine. My first assumption was that version 14 had updated my .pvm file so I got out one of my backups and copied the old .pvm file from version 13, but I still got the same error and I have now begun to worry that I can no longer use my virtual machine, even backed up ones, with version 13. The only other thing I can think of is that version 14 updated some of my Library files and folders and they are what might be causing the error but before I wiped out all of my Parallels Library folders and files I thought I should ask. What can I do to get version 13 running? At this point, with the swapping of virtual machines, I am not even sure version 14 will run properly and I do not wish to create an entirely new .pvm file. Can anyone make any suggestions?
