I can repeat that issue. Procedure:
Install a single CM12 SP1 primary on Server 2012, SQL 2012 SP1CU6 Install CU2 Install the agent on the server. All is ok. Do the exact same with CU3, once installing the agent I get this: MSI: Setup was unable to register the CCM_Service_HostingConfiguration endpoint The error code is 80041002 It never recovers from that. Anyone seen that or ideas?
