Installing Endpoint Protection Site System Role SCCM 1806 on Server 2016

[svariell]

I'm currently troubleshooting the logs, but because my SCCM Primary is installed on Server 2016 and SCEP doesn't install.  How do we get this to work?

Here's the messages I'm getting from looking at Site Components in the Console:
Site Component Manager failed to install component SMS_ENDPOINT_PROTECTION_CONTROL_MANAGER on server & SCEPInstall.exe returns error 0x8004ff73.

I ran into this issue also, turns out Windows Defender was not installed on the server due to another anti-Malware client being installed.  I uninstalled the "company required" anti-malware from the server, installed Windows Defender and the endpoint protection point installed on the primary site server without issue.
