2.2.2 Upgrading the Desktop Management Agent
The version of the Desktop Management Agent that shipped with the original ZENworks for Desktops 4 Program CD (setup.exe) is no longer supported. You must not attempt to upgrade from that version of the Desktop Management Agent.
You can upgrade the ZENworks for Desktops 4.0.1 Desktop Management Agent (and its functionality) and the ZENworks 6.5 Desktop Management Agent by installing the ZENworks 7 Desktop Management Agent.
Installing version 7 of the agent uninstalls older versions of the agent and enables ZENworks 7 functionality on your managed workstations.
