Installed Failed: Validation Failed - What is the issue?

Unity Engine
1

I am redownloading Unity on my Laptop. I had no issues with the HUB (love the new presentation) but when trying to install an editor, I get stuck in a loop with a “Installed Failed: Validation Failed” error. I tried going back to the previous version of the Hub and that did not wok. I also tried previous editors and that didn’t work either.

Any suggestions?

No one knows how to solve this issue?

Same here. Any ideas?
…aha it may have something to do with Admin rights. I’m using a non-Admin user in macOS…I’ll try again as Admin.

Edit: seems to work as a MacOS Admin user.

i’ve got the same issue… trying to get vis studio + documentation, but it says:
Editor application

Install failed: Validation Failed

any solutions to this?

I had this same installion bug on my M1 Mac—until I a) set my account to admin (not ideal for security!) and b) manually created the folder structure Applications/Unity/Hub/Editor. Now I have Unity 2021 and Visual Studio installed.

Except I still can’t install the documentation: “Download failed: Validation failed.” This is with the latest 3.0.1 Hub update.

I’m guessing I need a similar workaround: to manually create the directory(s) where documentation goes… what are the exact folder names/locations for that? (I tried creating a folder “Documentation” within the specific editor version’s folder, but no luck.)

TIA!

Mac Os Monterey, installing the 2021.2.16f1 silicon.
I had the folder Applications/Unity/Hub/Editor from previous installs (I recently changed macbook and removed previous installs before migrating), however the permission were read only for everyone. I changed it to read write for everybody and it worked.

Thank you for the hint about the folder
