Editor application Install failed: Validation failed
Someone please help, I've been stuck since forever just trying to update.
I HAD TRIED:
1) running unity hub as admin
2) disabling firewalls & antivirus
MY SPECS:
OS: windows 10 version 21H1
RAM: 8 gb
HDD: (23.0 GB free) of 232 GB
CPU: Intel(R) Celeron(R) J4105 CPU @ 1.50GHz
GPU: Intel(R) UHD Graphics 600
I currently use:
Unity Editor version 2019.4.2f1
Unity Hub 3.0.0-beta.2
My internet speed is fine.
If this can't be fixed, is there a manual way I could install the latest unit editor without using the hub? like through zipped folders or something?

I had the same error "Install failed: Validation failed" when trying to install the Editor via Unity Hub as a non-Admin user on MacOS (iMac 5k end 2015, Big Sur 11.6.1). I re-tried as an Admin user and it perfectly worked. Filed a bug report. Maybe this applies to Windows as well(?)
