Unable to activate Knox Guard commercial license

Last updated August 13th, 2026

Environment

  • Knox Guard
  • Commercial license

Overview

When you attempt to activate a commercial license, you may encounter the following error message:

The premium license you are adding has been registered. Please try again.

Cause

This issue occurs because you already have a Knox Guard Advanced license active in your tenant. Due to licensing restrictions, a commercial license can’t be added if a Knox Guard Advanced license (either Commercial or Trial) is already active in the Knox Guard console.

Resolution

To resolve this issue, you can either:

  • Remove the existing Knox Guard Advanced license from the console.
  • Contact your license reseller to upgrade the purchased commercial license to a Knox Guard Advanced license.

If you’re still experiencing issues, submit a support ticket.
