Hi!

I’m using Unity 5 Pro. I just installed Windows 10 on my desktop and laptop. On the laptop I was able to return my license and reactivate it. When I try exactly the same thing on my desktop, however, it won’t work. What happens is the following:

  1. I click the Unity icon. It sais “Would you like to deactivate this license and re-activate?”. I click yes.
  2. It sais “Re-activating - returning current license”.
  3. Then a new “Would you like to deactivate this license and re-activate?” dialogue box appears(!?). I click yes again.
  4. It sais “Unity license returned” and my only option is to click “quit”. Then it all quits and if I click the Unity icon it starts over again.

I even tried uninstalling and re-installing Unity altogether and deleting the C:\ProgramData\PACE Anti-Piracy-files as I read in one forum thread, but the issue prevails.

When I check my licens in my profile online, it sais I have only one activeted.

I would be very greatful for any help!

Ok! I solved it myself after about 1 h of searching on Google and trying different methods. The solution was to delete the .ulf file called something like “Unity_v5.x.ulf”

From http://docs.unity3d.com/Manual/UnityActivation-Overview.html, i found:

Where is my Unity 5.x license file stored?

  • /Library/Application Support/Unity/Unity_v5.x.ulf (OS X)
  • C:\ProgramData\Unity\ (Windows)
  • C:\Users(username)\AppData\Local\VirtualStore\ProgramData\Unity, if Windows User Account Control (UAC) has restricted your access toC:\ProgramData\Unity. (This can happen if the folder is deleted or Unity is started with administrative permissions first time.)

Hope it works for anyone else with the same problem!

I bought a licence key for Windows 10 Professional from the website “licence-activation” and now I am working on my computer with no problem. The key is original, and the licence is authentic. I suggest you this website.
