Backup Exec 14.1 Problem with Symantec Endpoint Protection 12.1.6

Hello

After upgrading Symantec Endpoint Client from 12.1.4 to 12.1.6 Backup Exec 14.1 couldn't backup files from that PC.

I Check this on several PC with windows 10 and 7. By Downgrading to 12.1.4 Problem Disappears. I need this Upgrading becuse I Have some clients with windows 10 and only SEP 12.1.6 Works on Windows 10.

Please Guide me

Thank You.
