Endpoint Protection

So we are in the process of upgrading our clients from SEP12RU6MP7 to SEP14RU1.

After the initial restart when installing the new version, IE11 is not starting up anymore.
Error Message:

iexplore.exe
The application was unable to start correctly (0xc0000005). Click OK to close the application

Event Log:

Faulting application name: iexplore.exe, version: 11.0.9600.18838, time stamp: 0x59e1b492

When disabling the Memory Exploit Mitigation policy, everything works fine again.
The policy even was set to "Set the protection action for all techniques to log only". Bummer.

So, what's the issue here?

Hello,

I would suggest you to create a case with Symantec Technical Support Team.

Does an exception work?

May need to contact support.

I already checked the logs, but no entry/event from any client.

Probably an issue for support.
