Novell ZENworks 10 Configuration Management with Support Pack 3 - 10.3 Installation - Agent
Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1 Management Agent
Situation
The message "This install has detected a previously installed version of ZENworks Configuration Management. To continue with this installation, please uninstall ZENworks Configuration Management first. " has several possible causes, including trying to install a new ZCM agent on a device that already has the agent installed.
This TID covers two possible error scenarios, ensure that one of these causes is applicable before trying the workaround/fix.
Scenario 1:
* Deploying ZCM 10 agent to device that has the agent from ZDM7SP1IR4aHP2 or ZDM7SP1IR4aHP3 (version 7.0.173.91015 or 7.0.173.100104, see TID 3546801"How to check which version of ZENworks 7 Desktop Management you have installed ")
* ZCM 10 has a full license, or the ZCM 10 agent is configured to enable features other than just Asset Management (see https://www.novell.com/documentation/zcm10/zcm10_discovery_deployment/data/bjfvxom.html)
ERROR: "This install has detected a previously installed version of ZENworks Configuration Management. To continue with this installation, please uninstall ZENworks Configuration Management first. "
Scenario 2:
* Upgrading ZDM7 agent from ZDM7SP1IR4aHP2 or ZDM7SP1IR4aHP3 (version 7.0.173.91015 or 7.0.173.100104, see TID 3546801"How to check which version of ZENworks 7 Desktop Management you have installed ")
* ZCM 10 agent is already installed, with only Asset Management enabled (see https://www.novell.com/documentation/zcm10/zcm10_discovery_deployment/data/bjfvxom.html)
