I accidentally deleted my old Parallels Windows 10 trying to free up space since my iCloud saved it in it's folder so when I deleted it, it took Windows 10 with it. I had to reinstall the entire thing and now I'm at the point where it says to "Activate Windows", but it keeps popping up with an error saying that the code that I used for the installation is already being used (by my old Parallels Desktop). Is there any way to help it verify that the computer that I'm using is still the same PC?
