Office 2016 applications crash when Endpoint Protection is installed
Last Updated August 17, 2017
On systems with Symantec Endpoint Protection (SEP), Office 2016 applications (specifically, but not necessarily limited to, Outlook and Word) crash. When you analyze the process crash dumps, you find that sysfer.dll is injected in the processes.
The process crash dumps show that the issue occurs when Office 2016 applications are initializing Nuance Power PDF Converter. Sysfer.dll is injected into processes as a matter of course; it is actually the many calls by Nuance's NPDFCG component that lead to a stack overflow and consequent crash.
