Greetings,
This has happened a few times now over the last couple of weeks. At first I thought it was just a once-off bug, but it keeps coming back and I can't see any patterns to identify the cause or trigger.
Sometimes when I start a Deployment from the Software Center the Status gets stuck at "Installing" and never moves beyond that. It has happened for OSD task sequences as well as Package/programs. In both cases the same Deployment works on other machines, or has worked on this same machine previously. It's not always the same programs, and there seems to be no particular pattern I can find to cause it.
Restarting the SMS Agent doesn't resolve, it just comes up as "Installing" again after the agent has restarted. I've tried clearing the adverts from the client and no difference, restarting the computer also makes no difference... it just comes back as "Installing"
If I remove the computer from the deployment, it dissapears from the Software Center, and when I add the deployment back again it re-appears in Software Center as "Installing" again.
Doing a client repair (ccmrepair) doesn't fix it. Doing a client re-install (with always re-install) doesn't fix it either. I have to completely remove the existing client and reinstall to clear the problem, but that makes the client then appear as a completely new device in CM12 so that's not a very reasonable resolution.
The only log entry I can find that seems to indicate an error is in execmgr.log where an entry saying "OnContentAvailable invalid request GUID handle" appears several times. I have no idea what it means. Running the same deployment on another computer works fine.
Clients are all Windows7 SP1 32bit.
