We are upgrading our pre agent from 11.2.3 to 11.4.2. On a few computers, the upgrade fails. When looking at the computer, the agent is there but it is not registered to anything. I cannot uninstall by normal means, so I run the zenworks cleanup utility, which uninstalls the program. When I try to manually install the new pre agent, I get an error that states "ZENworks PreAgent Error: UNknown PreAgent Error, Check the Application Event Log for more details"

I have had to re-image about 2 computers due to this error, and we've only just begun pushing out the new agent to about a thousand computers. I'm not sure which logs to look at, and even what I would be looking at in the logs.

Has anyone experienced this and possibly have a fix?
