After you have received a license file from Vicon Support, you must activate it before you can start using Vicon Shogun Markerless.

**To activate a license:**

1. Check your email for a message from Vicon Support. The license file (named *ShogunMarkerless.lic*) is attached to the email. If you have not received a license file, request one as described in [Request a Shogun Markerless license](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless118/pages/545523728).
2. Save the license file (**.lic*) to the Windows desktop of the machine for which you have a license (or any other suitable location).
3. Start Shogun Markerless and in the **Vicon Product Licensing** dialog box, select **Activate License**.
4. Depending on whether you are using the file as it was received from Vicon Support or as a text string copied from the file.
  - In the **License File Activation** field, type or browse to the location of the license file (*.lic*) and select **Activate from File**;   
or
  - Copy the text to the **License Activation string** field and select **Activate from String**.
5. Click **OK**.

> ✅ **Tip**   
> ✅ You can only deactivate a network license from the relevant license server machine, not from any of the client machines.
