Unable to activate Knox Guard commercial license

- 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.
