Install issues with Safeguard Disk Encryption

I'm a first time user with Disk Encryption, and have followed the install guide to the letter; creating a default policy and the subsequent deployment MSI package.

Ran the  guide specified pre-requiste SGxClientPreinstall.msi before attempting to install the Default Package.msi

However when I go to install the default package I am returned the error;

Please install one of the SafeGuard Enterprise Modules first.
Contact your support personnel.

I've logged in a a local admin and with domain admin credentials and been returned the same error.

Also tested with & without a reboot between the preinstall file and the default package.

Has anyone else experienced/overcome this issue?

All help much appreciated!!!!!
