Symantec Endpoint Protection 14 RU1 MP2 to 14.2
This is a known issue with the Application Hardening feature in SEP versions 14 RU1 MP2 through SEP 14.2
This issue will likely be fixed in SEP 14.2 MP1
Please upgrade Symantec Endpoint Protection Manager (SEPM) and SEP clients to this newer version or reinstall SEP without Application Hardening
NOTE: Simply turning off Application Hardening will not resolve the issue
