I am trying to apply a temporary time-limited key for our organization to a Cache Server that I built out a few weeks ago for testing purposes. When I navigate in the portal to activate a new license key, I get this "ERROR #8610: License keys are not accepted on a Single User (SU) platform."

Is there something I need to do for this system in order to make it compliant for the key or do I need to request a new key from InterSystems that will work for this system? I didn't turn up anything on the web site here or via Googling the error and error text.
