KACE Product Support

I recently ran into the same issue during a managed install. What happened in my case was there was a user prompt in the installation caused by a new process running that was not present in my test enviroment. So the managed install kicked off when users weren't logged into their computer and it prompted for them to stop the offending software but of course got no response. The intallation just hung there and log everytime the computer checked in would just say kdeploy is already running.  I tried creating scripts to restart the computer and push it to the label having issues but they wouldn't reboot, I'm guessing because Kdeploy was running and the agent was waiting for that to finish before running the pushed scripts? anyway it was a software installation problem for me. hopefully that can help you track down your problem

I ended up conecting to the machines useing psexec and forcing a reboot that way to "unstick" it

I have never seen this.  What it sounds like is that the KDeploy process is already running on your machines, so it can't start a new process to deploy other managed installs.  It may be that something you deployed is stuck on the machines still trying to run, so it can't start a new install.  I would contact support directly to take a look.
