Hello, I am running Catalina on my Mac. I have installed Parallels 12 and trying to "upgrade" to Windows 10 since there is no support for 7 anymore. I have tried doing a fresh install with a USB Thumbdrive as well as doing it with an iso file like I did before. Both are getting hung up with a black screen and "Parallels Wizard" showing at the top with a spinning wheel. This ran all last night last with no progress. Please advise.
