Обновлено: 06.07.2024

I reinstalled windows 10. I downloaded unity hub from the official site. Running unity hub I saw the error "You have no valid license".

There are 2 buttons "manage license" and "dismiss" on the error. I click on "manage license" and I get to the "License management" page in the Unity hub settings, I click on Activate new license "select" Unity personal "further on" I don’t use Unity in a professional capacity "and click" Done And a new error appears failed to reach unity license server, after that I return to the" License management "page in the settings Unity hub, and click on "Manual activation" further on "Save license request" And nothing happens. I tested everything!

Issues with returning licenses

If you encounter any error codes or other problems while returning your license, they might be caused by the following:

- The serial number you were using on the machine.
- The (local network) name of the machine that died.
- The order or invoice number used to make the purchase.

I finally found a way to fix this problem.

First of all you have to know that the issue was with the license, it didn't activate properly, so it just keeps trying to activate again and again, and that's where the bucle was.

To solve this, i follow some steps made by myself, that came from a lot of research and combining some tutorials for others problems.

The first problem was I log-in only once, the first time I installed. After that I was unable to login again even with reinstall and remove registry. So I couldn't stop the bucle.

To fix that you need to uninstall Unity, remove registry (Ccleaner for example) and remove some hidden directories manually:

After removing all those files, you can have a clean install of unity, if you don't remove those, it will keeps login in on the same acc and keeping the bucle on.

So, after doing that the bucle will stop and it will let you login again. First problem solved

Now if you log-in the bucle will happen again, so we need to activate the license without login in. And we're doing it with the offline activation.

Unplug your ethernet, disconect from wifi, whatever, just make sure you don't have connection.
Open Unity and check that says "No connection: Quit or Manual Activation".
Click "Manual Activation" and download the License Request.
Close Unity and connect your internet.
Go to the official Unity Manual Activation Page and upload your Request File.
Download the aproved license, it will request you an Unity account.
Unplug again the internet and open Unity on offline mode.
Click "Manual Activation" and upload the Aproved License.
Make sure you have now access to Unity on offline mode and close it.

Second problem solved: License activated.

Now you only need to connect again your internet, then open Unity and you will see an activated license without login-in, so you can now log-in with the account you used on step 6.

And now the problem is solved. You have the activated license and you're logged-in.

It tooks me like "2 days" to make this solution for this poblem, hope i can help someone with this tuto and save ur time.

I reinstalled windows 10. I downloaded unity hub from the official site. Running unity hub I saw the error "You have no valid license".

I just install Unity, log-in via google and had that error.

Now, the bug appears with not even login in.

I tried to reinstall, remove registry and it stills happen with not even login in anymore.

There's the link where you can see the bucle it keeps doing.

As you can see it keeps refreshing the license screen like it's trying to load something.

Thank you for any help you can provide.

Answers to other questions

Question:	Answer:
How many machines can I install my copy of Unity on?	Every paid commercial Unity license allows one person to use Unity on two machines that they have exclusive use of. It doesn’t matter where the machines are physically located or what operating system they are running.

Educational licenses sold via Unity or any one of our resellers are only good for a single activation. The same goes for Trial licenses (Unity 4.x only), unless otherwise stated.

The free version of Unity cannot be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000.

If you are a Legal Entity, you cannot combine files developed with the free version of Unity with any files developed by you (or by any third party) through the use of Unity Pro.

Activation issues

If you encounter any error codes or other problems during the activation process, they might be caused by the following issues:

You must return your license before you switch machines. You must also return your license before you make any hardware changes or OS changes to your machine. If you fail to return the license, the Unity license server sees a request from another machine and informs you that you have reached your activation limit for the license.
