To reinstall the previous version of the protection agent
-
In DPM Administrator Console, click Management on the navigation bar, and then click the Agents tab.
-
In the Actions pane, click Refresh information to update agent status.

Click Advanced.
Note The Advanced option is enabled only when more than one version of the protection agent is available for installation on the selected computers. If enabled, you can use this option to roll back to a previous compatible version. -
In the Advanced dialog box, select the previous version that you want to install.
Note If the previous version that you want to install is not displayed, it means that this previous version is not compatible with the currently installed DPM software. To roll back to a previous version that is not displayed, you must first roll back the DPM software. -
On the Enter Credentials page, type the user name and password for a domain account that is a member of the local administrators group on each of the selected computers.
-
On the Choose Restart Method page, select the method to use for restarting the computer after the protection agent is installed.
Important Workstations do not require a restart when you install the protection agent. Servers must be restarted before you can start protecting data. This restart is necessary to ensure that the protection agent gets installed correctly. After restart, it might take a few more minutes before DPM can contact the computer because of the time required to start services. -
On the Summary page, click Install Agents to proceed with the installation. DPM installs the previous version of the protection agent that you selected.
A status box is displayed to indicate whether the installation is successful. You cannot close this box until after installation has either succeeded or failed.
