Notes:
- Before reproducing the issue, with provided steps, it is advisable to save a copy of the file, so that later the license can be restored.
- Reproduction steps are simulating hardware changes.
- After performing hardware upgrades, the license is no longer valid. As a result we get a “License Error” dialog box with the message: “No valid Unity Editor license found. Please activate your license.”. The message is vague and doesn’t provide much assistance in figuring out what happened.
