How do I activate my license?


  • I have not used Unity before and would like to know how to activate my license
  • I would like to activate Personal, Plus, or Pro
  • I have used Unity Personal, but would like to update the Editor to my new Plus or Pro license.


There are a couple of ways to activate, depending on your network situation.


The fastest way to activate is online. Guidance for this can be found here

If you are in a secure network environment, or receive an error while activating, it may be due to a connectivity problem. Please try Manually Activating. If this does not work for you, please send the details along with screenshots of any errors received to Support.

If you have used Unity Personal, or a different Pro/Plus license key, in the past you need to update your Editor to input your new license details. To do this, please follow this process:

  1. Open the Unity Editor.
  2. Sign in with your Unity account.
  3. Open a project.
  4. Press the 'Unity' button (or 'Help' if you are on a Windows machine)
  5. Press 'Manage License'
  6. Select 'Activate new license' and type in your new Unity serial number.

For guidance on how to locate your license serial number (Plus, Pro and Enterprise users only), please see this article.

    I've been fighting with mine for a few hours tonight and I finally got it to work by deleting my license files (*.ulf) in C:\ProgramData\Unity

    Then restarting Unity and it asks you to activate your local copy again.

    Hi there,

    The process is still working from my testing just now. As Mike has said, any old license files may cause this process to not work so clearing out any pre-existing license files before completing this process may resolve any issues you have.

    If you still get any issues, please don't hesitate to raise a support ticket.

    I downloaded Unity with a personal account and it never gave any chance to activate it. It directly tries to authenticate the license then errors... I tried multiple things nothing is working.

    I'm on a Plus license yet license activation is a never-ending issue. Almost every time I open Unity I have to re-activate, enter the serial and it says it's reached a maximum number. Then I close it, open again and sometimes it works, sometimes it doesn't. I think there are some really serious issues here and it's very frustrating.

    Hi Shahin,

    Unfortunately, we do not sell licenses for specific versions. If you would like to use this version, the current subscriptions we have on offer do work with earlier versions, as an active subscription lets you use whichever version of Unity you wish.
