Delete the entire “Licensing” folder under Unity’s installation folder (like “**D:\Program Files\Unity\Editor\Data\Resources**“).

Good ! Thanks

Enabling the network adapter fixed the issue.

Works for me

The problem seems to be stemming from network adapters. I currently only use the ‘wifi’ adapter on my PC - but was using the ethernet port to control a different project. I ended up disabling all but the wifi adapter and thats when the problems started (I did not realize it at that point) - I re-enabled the ethernet adapter and this issue went away.

OMG! This worked for me. <<SOLUTION: Enable all the network adaptors that are currently disabled in Windows>Network & Internet > Change Adapter Options >>.

I was using Unity 2019.2.17 with the latest Unity Hub and experiencing this exact problem. This has been happening for months, I’m so happy I now fixed it.

I’ll write a detailed bug report in case Unity wants to investigate

Bug title:
Unity hub cannot open any projects.

Hub Version: 2.4.3 (but this has been happening with older versions)

Bug Description

When attemping to open a project the Unity HUB, the hub would attemp to launch Unity Editor, but fail after 1 second, briefly flash “unity is already in list you cannot locate the same version” (this message only flashes for a fraction of a second) and then you are returned to the same Unity Hub window, with no Error message or description at all. I had to usue screen capture software and time my keystrokes to be able to capture what the brief error message said.

Solution I found:
Enabling all the network adaptors that were currently disabled in Windows>Network & Internet > Change Adapter Options

Had the same issue this morning, I upgraded to latest Hub (2.3.0). Spent hours trying to open my projects… but I was just booted back to the Hub again. Restarting, re-installing, nothing worked. And as other’s stated, I could Create a New Project, but not Load it…

Anyways, here’s how I fixed it:

1. Sign out of Hub and close it
2. From Task Manager → remove any Unity Hub process still running (I had 1 running even though it was closed!)
3. Find your license *C:\ProgramData\Unity* and delete the Unity_lic.ulf file
4. Start Hub again and Sign In
5. It should complain that you don’t have an active license (Go to Cogwheel in top right and choose License Management)
6. Choose Manual Activation and follow the instructions

Instructions for Manual Activation
(7. Save a License Request file on your PC)
(8. Go to the link provided license.unity3d.com/manual (you need to be signed in))
(9. Locate the Saved License Request and upload it. Then Download the new license you get. Place it somewhere safe)
(10. In Hub click Next and locate your new downloaded License)
(11. It should state that it was successfull)

12. Then open your project from the Projects list again and it should work

Really annoying problem, and the error message “Unity is already in list. You cannot locate the same version” that pops up for a few milliseconds was really hard to spot… also didn’t say anything about failed licenses. (I’m using Unity 2019.2.7f and 2019.3.5f1)

This solved the issue for me, but I didn’t have to manually activate my license, I just did it the normal way. Is appears to be that the license file is corrupted or something

Unity hub 2.4.5 and still the same problem like wt

[SuicideMachine]

This issue still exists on Unity Hub 3. I have it now and it’s really frustrating. The same issue as marcosbiagi - “Unity is already in the list. You cannot locate the same version” - where is this read from?!

I tried uninstalling Unity, removing everything in C:\Users that was related to Unity. Removing everything in Program Data, Program Files etc. as well as registry including firewall and this is still an issue - essentially nuke it to the ground and it’s still an issue.

I tried returning and activating the license… nothing helps. Only I could get it to start running by running scene directly.

Finally, I managed to get it running by activating my Wifi adapter. In a desktop! The wifi adapter that I have never used, cause it’s a desktop and I am always connected by a gigabit ethernet cable. Wanna fix it maybe?

(this lovely bug still exists in hub 3.1.2)

Thank you very much for this thread. I Was trying everything listed here, including disabling and unconnecting every USB dongle, but for me finally steps seems to be much simpler:

delete this folder:
X:\ProgramData\Unity
and this one:
X:\Program Files\Unity%UNITYVERSION%\Editor\Data\Resources\Licensing

reactivate licence in HUB, working.

If for some reason it’s not working, you can just open Unity scenes, but it’ll run Unity in Indie mode, so it is not useful for everyone.

I will copy this to every other helpfull threads here, it was wasted day and a half, thank you very much.
