Updated DPM 2012 R2 to UR9, all went well, updated the agents on all servers except one which wouldn’t update. Logged onto the server and noticed the DPMRA service was missing since we tried to update the agent as though it had tried to remove the old agent and errored. Thought ok i’ll uninstall the agent manaully via programs and features however this fails with error 1603. I am now stuck with a server where i can’t remove the DPM agent. Anyone know of a way to force remove it?
