I have a Parallels 13 and (on another, older, computer) a Parallels 10. I tried to move a 13 VM (an updated Windoes 10) and start it with Parallels 10, but no go. Is there anything I can do to make it possible to run the image with Parallels 10?
So, found this. https://forum.parallels.com/threads/cant-install-windows-10-into-parallels-10-vm.344161/#post-838022
