Bug UnityHub 3.7.0 Validation Failed

Hi,

I'm trying to install the version of UnityEditor 2022.3.22f1 through the UnityHub and showing a message error: "Install failed: Validation Failed". I have tried to install also other versions and getting the same error.

 

I have this issue, and deduced it to 100% a Unity bug (and not a local bug):

Code (JavaScript):

@Grabthesky Here's proof it's a bug and not you:

You can see Unity meant to elevate the process, but clearly failed due to their own bug -> if they were successful, UAC would've popped up (screenshot above); it didn't.

As a terrible workaround, reformatting will fix it (tested with Windows Sandbox), so it's not a server-side issue linked to your account:

As a likely-guess: Unity Hub likely messed up their permissions when downloading->installing->moving. Specifically: Since the logs show there was a UAC popup (when there clearly was no attempt made), it's likely someone commented out or removed an important step to *actually* trigger that UAC prompt. Or-- permissions changed between updates, possibly fixing it in a ninja update so that new users wouldn't repro it and users caught in between these updates *would* repro it, allowing Unity to play naive to pretend it's you and not them.

The fact is: If Hub would've trigger an elevation correctly, a UAC prompt **would** popup. If not, it's their own bug.

You could probably deduce it further, but it shouldn't be your responsibility to do Unity's QA work~ There's one working dir out there that Unity - not you - changed that has elevated privs that it shouldn't have.

There were probably 2 diff versions that handled UAC/dir perms differently -> Unity auto updated itself -> Perms mismatched

 

Grr, I found myself doing Unity's QA work for them, but:

Code (JavaScript):

1. {"timestamp":"2024-04-02T07:02:36.170Z","level":"error","moduleName":"UnityInstallerWindows","pid":28972,"message":"{ code: 'User did not grant permission.', message: 'The Hub does not have proper permissions to install Unity.' } Start-Process : This command cannot be run due to the error: No application is associated with the specified file for \r\nthis operation.\r\nAt line:1 char:1\r\n+ Start-Process -FilePath 'C:\\Users\\kenshin\\AppData\\Local\\Temp\\d8c3ae68 ...\r\n+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r\n    + CategoryInfo          : InvalidOperation: (:) [Start-Process], InvalidOperationException\r\n    + FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand\r\n \r\n "}

This tries to set UAC of a `%temp%` dir that doesn't actually exist. Someone probably forgot an `await` and tried to elevate perms of a dir that !exists.

 

If this is a bug with the Unity Hub, it is not exclusive to 3.7.0. I'm having this issue with 3.6.1 as well.

 

Then looks like the only way is to wait for a bugfix of the UnityHub. I have read many post about this issue and didnt find a way to fix it.

 

Hello, I'm also having problems with installing Editors or Modules for about 1 week now.

Based on other threads regarding "Validation Failed" I already tried so far:
- restart computer
- using different networks
- reinstalling the Hub
- using an older Hub Version (3.6)
- start the Hub as admin (but the Hub just opened as a black window)

Here are my latest logs after trying to install a module. For me it looks like there is a problem with the certificate.

WHAT A CHAMPION! Thank you!

 

I am a user from Japan.
UnityHub has not started for the past few days.
It freezes 100% of the time.
I found many similar reports on SNS since 4/19.
Has something been updated or changed in the specifications?

 

OR you could have rolled back to the last known working way of installing, because that way, you know, was working. It's not rocket science to start a process from an executable on Windows... millions of software products do this just fine all the time.

In fact, double-clicking the installer shows that it properly asks for elevation itself.

You're more than a software company, Unity. You are a company that makes software to make software. It has been almost a year that Hub has been worthless to me and my teammates to get any Unity Editor downloads.

Edit: And the beta you mention is not available to me through the beta channel.

12.  

Needless to say, my PowerShell is in perfect condition. We do most of our scripting with it.



and this appears to be what your error is caused by:


It should be (additional parameters as needed of course)


I don't know how an embarrassing bug like this can make it into a stable release and stay in it for >9 months, but here we are.

 

Enterprise software, at that. I saw the recent patch notes after 6 months in the making, and it was enough content for 1 mid level dev for a 40 hr week.

What happened?? Where's the rest? Is there really just 1 dev working 2 hrs/WK on this?
