Hi,
You will need the full retail installation media along with the product key. Since you already have a rollup installed, you will need to make a backup of the DPMDB (dpmbackup -db) - un-install DPM and retain replica, re-install DPM using retail media,
apply same UR3 update, then restore the DPM Database so you maintain your configuration settings and recovery points.
