I'm struggling to reinstall Unity after Hub crashed halfway through installing an editor version.

I have tried to delete the partially installed Unity - but I don't know all the locations to look, as any new attempts to load Unity are blocked by older files.

[![Error dialog: Unity 2021.1.16f1 Android Support Setup: Failed to delete old Unity Android Support installation files. Maybe Unity or some of its tools are still running?][1]][1]

There is no Unity running. I checked in Task Manager. I had made sure the directory was empty before I reinstalled. I also restarted the Hub before I started the new installation (just in case) then removed Hub, and after that all Unity versions....

Running Windows 10.
