Bug [Unity Hub 3.0.0-beta.1] Failed to delete old Unity Android Support installation files

I've uninstalled Unity 2020.3.13 and went on to install Unity 2020.3.14.
After some waiting I got the message that it "failed to delete old Unity Android Support installation files. Maybe Unity or some of its tools are still running?"



I've already closed anything else but the Unity Hub itself.

 

me too

 

Same problem here!

I reverted to Unity Hub 2.4.4 and I still can't install.

 

I had to do this:

I get that error every single time.

 

Had to roll back to the 2.0 version

 

This works for me for Unity 2021.2.0b6 (beta):

• Uninstalled my UnityHub 3 and some old junk files from a previous install in Windows Apps & Functions (uninstall).
• Downgraded to/installed UnityHub 2.4.5 (latest on Unity website)
  
• Deleted all temp files in `C:\Users\[user]\AppData\Local\Temp` named something with UnityHub
• Deleted the old Unity version in UnityHub, and then reinstalled it again.

 

I killed a process called adb,then delete old unity successful.

 

Hello guys, if you're using Unity Hub, you just need to abort, close Unity Hub and start Unity Hub again as Administrator, then retry failed downloads for that installation.
