What causes this error?

The system is unable to post changes to the FINAL Receipt as the Kitchen Display System (KDS) license is unable to authenticate as valid.

How do I resolve this error?

Attempt to refresh the licenses if you have had a valid license in the past.

1. Go to Start > Run and type licmanager.
2. Navigate to the Kitchen Display System tab.
   • The license will have a red 'x’  or a green check mark next to it, which identifies if a license is present. You can re-verify this by clicking on the reload button, or double-clicking on the license in question to trigger a status check
3. If refreshing doesn't work, you will need to obtain a valid KDS license from your MICROS dealer.
