    Same error when trying to add modules to an existing Editor. Did work once restarting the Hub as Administrator.

    I had it happen in hub 3.7.0 and on windows 11. Happened when I restarted hub to update to the latest version. Literally can’t do anything else right now cause I can’t install unity.

    I encountered the same problem on 3.5.2 and despite trying many different ways I always end up with the same error, however I do have to say that when I installed the downloaded file in the %TEMP% that unity version did work (for a while) and I could make a quick app and launch it on my phone, but a few days later it completely went crazy thinking all textures (that worked previously) have a negative or zero width (Including built-in sprites and fonts), so I simply uninstalled it and simply downloaded unity from the archives, but even then that project didn't work anymore, I had to recreate the project manually.
