I've been wracking my brain trying to figure out why ZCM 11 SP1 Adaptive Agent would not install on some of our machines that have an older image. Turns out that they had ZDM 7.1 HP 4 installed on them back in the day, and when ZDM was uninstalled, the uninstall presumably did not cleanly finish.

MSIList still shows:

ZENworks Desktop Management Agent

If I run:

MSIZap T! {5263A4C5-1452-44D1-B30D-CE1833828CFD}

and reboot, the machine completes the ZCM 11 SP1 Adaptive Agent install that was started a week ago, but that errored out. Unfortunately, as soon as a user logs in, they are prompted that the machine will automagically reboot in 5 minutes to complete ZENworks Adaptive Agent installation. Is there a way that I can tell the machine to not prompt for reboot, even though I launched the installer a week ago?
