I am currently running the ZDM 6.5 agent on my XP workstations and I also purchased the Novell Zen Asset Manager product, which has it's own agent on the workstations. Now the ZCM agent also does the functionality of the ZAM client. When I try to install THE ZCM agent it attemps to remove the old ZDM agent. This fails. The only way to recover from this is to reghost the workstation. If you manually first remove the ZAM then you can manually remove the ZFD client, then you can install ZCM. It appears that if you are using the ZAM you cannot instal ZCM because it will not remove the older client, even though it says it should, and hoses the workstations. Novell needs to look at this problem.
