Returning a license

How many times can I return a license and reactivate it. We currently have every pro version on our license, but need to use that one on 3 different machines (our test machine, my windows machine, and a mac for iOS builds). Can I keep returning my license on my windows machine and mac machine to use them when I need them, or is there a certain amount/time frame I am allowed to do it in?

so you need to email support@unity3d.com
they help you with that

now as i know they generally give you 2 seats for your laptop and computer

but if you explain it to them they might be flexible

essentially they want a unity license to be exclusively for an individual
so as long as its just for your use you should be good

Unity 4 Users can return their license on a machine they have access to via the process below:

  1. Open Unity 4
  2. Click “Help”
  3. Click “Manage Licence…”
  4. Click “Return Licence”

This must be done prior to reformatting or a hardware change. You must also have an uninterrupted connection to the license server. This does not tend to be the case when behind a proxy or being without internet connection.

Nope this solution does not work.

I still waiting for 10 min and the loading bar is most of the end.
