McAfee ePO isue when installed during RunSynchronous

[eschloss]

I have a fully automated Vista Enterprise install using Autounattend.xml and I am installing all of our line of business applications using the RunSynchronous commands. The issue I am having is with the McAfee ePO agent install. When it is installed as part of the RunSynchronous, Windows Defender blocks it from starting up at boot and I have to manually click Allow each time i restart.

If I don't install it during RunSynchronous and I wait until the machine is up and running, I can right-click on the install and select Run as Administrator and it installs fine (since it is a service the installer runs in Session 0 instead of Session 1).

I have looked at Defender and I cannot Enable this to run because Enable is always greyed out when looking at the application viewer.

I could disable Defender in my Autounattend.xml, but I'm trying to accomplish this wothout disabling Defender.
