"Endpoint Protection Agent not yet installed" on Windows 8 clients.

Hello,

I'm running a SCCM 2012 SP1 environment with System Center Endpoint Protection.

All of our Windows 7 clients are running SCEP just fine and shows up under "Active clients protected with Endpoint Protection"

The problem is that our Windows 8  clients are stuck with the status "Endpoint Protection Agent not yet installed", even though SCEP have been installed on them and is working fine.

Any help would be appreciated.

Thank you
