Issues with Unity Industry/Enterprise licenses occurred after upgrading from Windows 10 to 11, causing license files to disappear and projects to not open. The cause was improper license syncing during the OS upgrade. Resolution involves deleting local license files, logging out and back into Unity Hub, releasing legacy activations, and reassigning the serial number to restore normal project access.
Symptoms:
- Issues occurred after upgrading from Windows 10 to Windows 11 related to Unity Industry/Enterprise license.
- The same problem persisted despite taking several measures such as removing the existing Unity Hub program and reinstalling Unity Hub.
- XML license files kept disappearing after rebooting or refreshing.
- Projects in Unity Hub were not opening normally.
Cause:
The problem stemmed from the Unity Industry/Enterprise license not syncing properly during the Windows OS upgrade process. This resulted in continuous release of the license and issues with license file persistence.
Resolution:
To resolve the issue, follow these steps:
- Erase the node-locked license file remaining in the local machine:
- Windows Route: %LocalAppData%\Unity\Licenses\[Serverid]_[SubscriptionInfo]_[LEASETOKEN].xml - Ensure there are no licenses on the [Preferences]-[Licenses] page after deleting the .xml files and logging back into Unity Hub.
- Log out from Unity Hub if you're already logged-in
- Release all legacy activation history assigned to a specific user account and assign the same serial number to account once again
- Go back to Unity Hub and log-in with your ID/Password credential
- Verify if the Unity project opens normally in the existing Unity Hub.
By following these steps, you should be able to resolve the issue caused by recognizing a wrong license from local machine.
