Am I able to take the key off my computer now and put it on my new computer? I read educational ones are for 1 computer only but I need it on my other computer.
Are you sure it didn’t mean one seat? As in one per person?
Or one computer at a time?
I don’t see Unity telling you that you have to use that computer forever or buy a new license.
Try this
Open Unity click on Help then manage license.
You’ll see where it says return license.
Then I am pretty sure that you just reactivate your license on your other computer.
The student licenses can only be installed on one computer at a time. You can return the license like Nubz said although it’s only possible to have it on one at a time. You can change it as much as you like though.
