Bug Report: Unity Hub 2.2.1 fails to install or delete editors

Steps:
- Open Unity Hub 2.2.1
- Login to account
- Try to install 2019.3.0.f1. Result: Noop after confirming EULA
- Try to remove previous 2018.3 build. Result: Noop after hitting remove button.

Tried:
- Uninstalling unity hub, all editors, restarting computer, reinstalling unity hub
- Logging in and logging out

Looks like the issue is with the install daemon not having the correct permissions:

I am getting a very similar issue as well. My anti virus keeps detecting trojan (execute.bat file) whenever I try to remove or install a editor. When I disabled it and tried installing and uninstalling nothing happens. No download starts for a new editor and old ones just sits there doing nothing.

I have tried uninstalling Unity Hub and reinstalling, but the same thing just happens. I'm just going to look for an older version to revert to so I can get those functionalities back.

 

Have exactly the same problems with UH 2.2.1.

Here is 2.0.4 and it works for me:

Thanks for the link now I can remove some outdated Unity editors I don't use anymore, and get the latest one.

 

Cant install Unity 2019.2.16f1 with UH 2.2.1.
Unity hub download it but do nothing when try to install it.

 

Same as above, Cant install Unity 2019.2.16f1 with UH 2.2.1
I selected the editor, deselected visual studio since its already installed
I selected the Android, WebGL and Windows modules.
Sat through the Very UNINFORMATIVE download, the only thing showing is the download progress bar (We cant get like what its downloading/installing, download or install progress rate? Download speed?)

Once it was done, it just went back to the No Unity Version screen.
I checked the ProgramFiles/Unity/Editor folder and theres only a few .dll files there, no folders

Jeeez man! I needz to Code!!! I am having a massive panic attack!!

 

same here. UH 2.2.1 trying install or uninstall any editor edition, noop.

 

i have the same problem. using Unity Hub 2.2.2. Hub auto-installs 2018.4.14f1, but can not complete install of 2019.2.17f1. Hub downloads 2019, gets stuck on install for about 15 minutes, then deletes 2019. to get around this, i directly downloaded the 2019.2.17f1 EXE and installed it- everything went well. but now the Hub will not allow me to boot 2019- when i start 2019 directly, it opens Hub, and appears to be stuck on the install (even though 2019 was installed previously). i dont see a way to get past this point to open 2019.2.17f1.
pc: Win 7 Ult, SP1. 64 bit os. 4ghz amd 8350. 16GB ram. 113 gb free hdd. default browser is firefox 71 64bit.

 

Same issue on 2.2.2 for me. It's driving me crazy, and now I'm unable to use Unity Editor at all. Haven't found any workaround yet. I'm not using any anti-virus except for the default windows defender. On linux it works fine for me, but my project with ECS crashes the editor every few minutes (separate issue for a different thread though).

 

Øh ,god ，I have the same error。my unity hub Can't install unity ,What should I do to successfully install 2019 ？

 

I am having the same problem

 

I solved this problem by adding PowerShell to the environment variable
