Deploying Safeguard Easy 7.0 to Windows 7/8.1 with SCCM 2012 R2 + MDT 2013 Update 2

Hello,

I'm currently deploying new task sequences to our PCs.
We are using Windows 7 / Windows Embedded 8.1 depending on what kind of hardware it is.

We have Safeguard Easy 7.0 and we have done this successfully with our previous setup of Safeguard Easy 6.0.

I can deploy the software and see that Preinstall, Client + Configuration package is installed but the disk is never automatically encrypted after this.

We do not use bitlocker.

This is the install parameters I am using withour SCCM 2012 R2 Task Sequence.

Preinstall package:
msiexec /i "SGxClientPreinstall.msi" /qn /Log "C:\presophos.log"

Client install package:
msiexec /i "SGNClient_x64.msi" /quiet /log "c:\SGNClient.log" NOATA=1 ADDLOCAL=Client,FileShare,SectorBasedEncryption,SecureDataExchange

Client configuration package:
msiexec /i "SophosSafeGuard_Company_x64.msi" /q

The result is that I can see in the control panel on a deployed PC that the packages are installed.
Before it automatically started encrypting the disk on first logon, now nothing happens.
We only want the local system disk to be encrypted (not USB drives etc).
Is there a installation parameter I am missing?
The client configuration package has the correct policies deployed to it.

Best regards,
Sebastian
