Question by RealMTG · Jun 19, 2015 at 11:48 PM · unity 5license

Unity 5.1 never stops checking for license

Hi

I upgrade to Unity 5.1f1 and it worked in the first place. But now when I decided to do some work I just got this message: "Checking license. Unity is checking your license authorization - stay tuned!". It has been like this for 30 minutes now. What causes this? Is there any official word from Unity? (Checked Unity's site and Twitter)

Here's some questions that might get asked that I can answer now:

  • I do not use a VPN

  • I do have Internet access (or else I wouldn't be able to type this)

  • I have tried to restart Unity

  • I have not installed any special software (like Unity pro crack. I would never even think about this!)

  • I have tried to reinstall Unity.

I'm getting this as well. No VPN, no crack's just pure vanilla Unity 5.1f1. Reinstalling does nothing, and neither does removing license files from the Unity app data folder.

I've got this ridiculous bug right now, thanks to Windows 10 pro upgrade.

Dear Unity people, this is a free, personal license - why on earth do you have to have this online checking thing - that then breaks? Surely it'd be better to just do it once and never bother wasting bandwidth with it again?

I just had the same. I solved it by disconnecting from the internet when the "Checking license"-screen hangs. It will cancel trying to license automatically and offer you to start the manual licensing process. I followed this guide and now I can use Unity: https://unity3d.com/unity/activation (2nd chapter).

After around 10 $$anonymous$$utes of pulling out the internet cable it worked. Thank you!

A small caution for anyone doing this. We activated our machines using the manual activation on the recommendation of Unity staff on the forums.

Neither our old laptop or surface pro tablet would return the licenses, the online license return just sits and does nothing forever. We now cannot move the license to a computer, and we've submitted several support requests without a response starting over a week ago. Leaving us in a state for over a week now where we actually have to copy our 11GB build package to a USB stick and run it to an old laptop anytime we want to do a build (using community is not only against their TOS, but leaves that hideous 1990's-esque splash screen. which we paid 1,500 to get rid of).

If you decide to pursue their manual activation technique, you do so at your own peril and open yourself up to not being able to use the software in the future.

Have you deleted the unity folder in ProgramData (note, not program files or appdata) and tried the activation again?

That would be a very bad idea.

The average manual activation is storing it's activation file there. $$anonymous$$eep in $$anonymous$$d this answer specifically suggests manual activation, not the standard 'net enabled, anyone can self fix activation.

If you delete that file you will never be able to regain that activation without going through support. You will never be able to release that activation from your record. Ever.

Regardless the issue of using manual activation is NOT activating. Rather never being able to deactivate and using up your only two entries by doing things like deleting your ProgramData folder.

The manual activation solution may work (for some), but the permanent and much quicker fix is to delete the ULF file in the ProgramData folder.

Right Click>Run as Administrator seemed to work.

Give that a try.

Got that error. Reinstalled, tried offline activation and was getting really frustrated since nothing worked. Running as ad$$anonymous$$ solved it. Thank you so much!

I have similar issue with Unity 5.4.3 - 64Bit. After major update for Windows 10 (build 10586 - you can check your windows version by run dxdiag), my Unity get this license error. Nothing like delete license, load license locally using license generated from web, and run as administrator works. The weird thing is, using 5.4.3 - 32Bit works. Here what i do:

  1. Uninstall Unity 5.4.3 - 64Bit.

  2. Download Unity 32 Bit. Don't use the unity installer, it will download the 64Bit build. Download it from the archive by click the dropdown and choose Unity 32Bit. You will get UnitySetup32-5.3.4f1.exe file.

  3. Install Unity 32Bit, Start unity, Login if prompted, Choose license. At this point, you can use Unity.

  4. Restart Windows and run Unity to check if the license working. The weird thing is, when I restarted Unity 5.4.3 - 64Bit, the working license got error. It seem the license not loaded to the memory. So, after install Unity 5.4.3 - 32Bit, please restart to check if the license is works.

  5. After the license worked in 32Bit, if you prefer the 64Bit build, you can uninstall the 32Bit and install the 64Bit build. Don't delete the unity license in ProgramData, the 64Bit Build will use it!

  6. After installing the 64Bit build, In my system, the Unity is work without displaying those nasty license error.


Afterthought

I think the error is the 64Bit build generated error license file and failed to load it since the 32 Bit build generate it correctly.

This maybe not working in your windows 10 system, since I do extra step like updating the VGA driver and remove adware using Adwcleaner. So I don't guaranteed it working in your system.

  • Just happened to me as well. Was licensed Unity Pro on 5.0, working fine. Upgraded to 5.1.1f1, hangs on "Checking License".

Tried offline activation process, upon loading signed license .ulf file, Unity told me the machine was a mismatch and to reactivate. Upon reactivating, hung at checking license.... ARGH.

Finally, quitting out of this then relaunching after manual activation finally seemed to work.

Not the most fun upgrade... yikes.
