"Unable to remove Service System Error: 1722 System Message: The RPC server is unavailable." error After Upgrading the DMRC Client to the latest version

Beginning in Dameware 12.2, this new version is not compatible with older agent versions. Agents must be removed, and Dameware version 12.2 installed again through the application or re-installed via the agent installer.

However, on this issue, the administrator is unable to connect to any target computer. When trying to remove/uninstall the agent services, getting an error:

"Unable to remove Service
System Error: 1722
System Message: The RPC server is unavailable."
