SEP 14.2 RU1 Scheduled LiveUpdate not running

Environment:  SEP 14.2 RU1, UNMANAGED CLIENT, Windows 7 Professional 64-bit

Issue:   Scheduled LiveUpdate not running at configured interval of every 1 hour after reboot

We have an unmanaged client running SEP 14.2 RU1.   LiveUpdate is configured to automatically run every 1 hour.  We can log on to the client, invoke the client's UI and manually run LiveUpdate from the client's Status screen.   LiveUpdate completes normally and the clients defs are updated.   We can see in the client's System Logs where 1 hour after the manual LiveUpdate is run a message - "Scheduled LiveUpdate switched to configured interval".   LiveUpdate runs immediately after this message is issued and at 1 hour intervals after that.  If we shut the client down (like for a weekend) and reboot later, the scheduled hourly update doesn't run until we logon to the client and invoke LiveUpdate manually.  This is an unmanaged client.  It never connects to the SEPM.

Any ideas?  Does anyone know if this is a defect in SEP 14.2 RU1?  Is there a SEP 14.2 RU1 update out there?

Thanks,

Wally
