[1703, cu] EndPoint Protection Deployment failed for Windows 10 via SCCM

[DJ-1701]

This only appears to be happening on Windows 10 devices. Windows 7, Windows 2008, 2008 R2, 2012 R2 all deploy fine.

 

In SCCM I am recieving the following:

 

Deployment State: Failed

Deployment Return Code: 0x80070643

Deployment Discription: Cannot complete the System Center Endpoint Protection installation. An error has prevented the System Center Endpoint Protection setup wizard from completing successfully. Please restart your computer and try again. Error code:0x80070643. Fatal error during installation.

Endpoint Protection Client Version:

 

Restarting doesn't help at all. Anyone have any ideas?

SCCM using the built in Windows Defender install on Windows 10 and 2016, so you don't need to install the endpoint client.

SCCM does install a component onto Windows 10, you can see if this successfully installs by going to C:\Program Files\Managed Defender.

 

Found out Sophos needed to be cleanly wipped from the machines including deleting reminates of C:\Program Files\Sophos, C:\Program Files (x86)\Sophos and C:\ProgramData\Sophos. Also pushed Endpoint Protection policy above SCCM for good messure. Now deploying fine.
