How to install Register.com certificates in SBS 2011

Purchase an essential security SSL Certificate from Register.com for remote.mydomain.com

I received the following certificate files from Register.com:

remote.mydomain.com.crt - Described by Register.com as the Doamin/End-User Certificate.
UTNAddTrustServer_CA.crt - Described by Register.com as Intermediary 1 certificate.
RegistercomSSLServicesCADV.crt - Described by Register.com as Intermediary 2 certificate.
ADDTrustExternalCARoot.crt - Described by Register.com as the Root Certificate.

Installed the 2 Intermediary  certificates just fine.

When I used the SBS 2011 Console "Add Trusted Certificate" wizard, I browsed and selected the
ADDTrustExternalCARoot.crt certificate and the installation of the certificate failed.

When I again used the SBS 2011 Console "Add Trusted Certificate" wizard, I browsed and selected the remote.mydomain.com.crt  certificate and the installation of that certificate was successful.

My question is where and what are the steps in SBS 2011 to install the ADDTrustExternalCARoot.crt  certificate
