Online activation

If your machine has internet access, you can activate your new Unity license online through the Unity Editor.

To actival a new license for Unity Plus or Pro, you must have a Unity Plus or Pro license, and your serial number, which Unity emails to you. If you don’t have a Unity license, speak to the Owner of your license, or contact Unity Customer Services.

Open the License Management window

If you already have Unity installed, open it, and in the top menu go to Unity > Manage License.

If you don’t have Unity installed, download and install the Unity Editor. Go to Download Unity to get the latest version. If you’re not sure which type of license you need, go to the Unity Store and view comparisons for Unity Personal, Plus and Pro.

Open the Editor and sign into your Unity ID. If you don’t have an existing Unity account, create one.

When you log into Unity for the first time, the License management window appears.

If you already have Unity installed, or if the License management window doesn’t appear, navigate to the top menu and go to Unity > Manage License.

If the license activates successfully, Unity displays a “Thank you!” message. Click Start Using Unity to continue.


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

  • Your machine might not have internet access.
  • Unity’s license servers might be down. See the Unity Cloud System Status Page for status updates on the all Unity servers.
  • Your firewall settings might be blocking Unity from sending and receiving data about your license file.
  • You might not have the correct read/write privileges on the machine to save the license file. This is a particularly common problem in workplaces and schools; contact yout IT administrator to find out whether there are restrictions in palce that might prevent the activation process from working correctly.
  • Major operating system changes or updates might affect your machine’s ID, causing your licence to stop recognising your machine. See the Unity Knowledge Base article I Have Just Updated/Installed A New Operating System. Why Is My License Failing To Activate? for more details, or contact Unity Customer Services.
  • For information on all potential errors and how to resolve them, see the Unity Support Knowledge Base. If you can’t find a solution, please contact Unity Customer Services for more assistance.

Note: You cannot contact the Customer Service team via the Unity documentation feedback form below. You must send a support ticket to Unity Customer Services.
