The Uninstaller and the Agentcleanup.exe both crash on Windows 7 Sp1
32-bit, so there remain lots of remnants especially regarding the ZESM

Is there any reliable method of removing them manually or a list of all
files and registry entries, which have to be deleted, because this
kills all efforts to reinstall the agent.

The uninstall and reinstall of agents has to be made much easier
otherwise you loose all management gains due to the complex procedures
necessary to simply reinstall an Agent.
