We are having an issue with a number of clients running Office 2013 H&B in a domain environment, after a click to run update.
It appears the update is ran in the background and after a reboot, the program files short of a few .DLL's are completely missing. Office still shows as installed through the control panel.
We have to use the office removal tool and reinstall program completely. System restore does not fix the issue.
These are Dell Latitude and the version of Office shipped with the machines as an OEM version. There was nothing pushed from the Dell update utility for Office.
They are running Avast AV and it is not affecting all users presently.
I've been on hold and getting transferred around Microsoft's support lines all day as Microsoft support can't seem to figure out which department should troubleshoot the issue.
Any assistance would be greatly appreciated.
