DPM Agent failed to install on Server Core

We currently have DPM 2007 SP1 installed and am trying to push the DPM client to a Server 2008 R2 Core server to backup our Hyper-V VMs.  Doing so generates this error:

Install protection agent on <dpm fqdn> failed:
Error 313: The agent operation failed because an error occurred while running the installation program on <dpm fqdn>.

Error details: Fatal error during installation (0×80070643)
Recommended action: Review the log files on <dpm fqdn>: [windir]\temp\msdpm*.log and take appropriate action. Retry the operation, and if the error persists, restart the computer and then retry the operation again.

To fix this I had to perform the following steps:

1. Install DPM Hotfix rollup 970867. http://support.microsoft.com/kb/970867/

2. From the 2008 server, run the DPM agent installation manually. (Ex. “\\dpmserver\c$\program files\Microsoft DPM\DPM\Agents\RA\2.0.8844.0\amd64\1033\DPMAgentInstaller_KB970867_AMD64.exe”)  Use the x86 if your machine is 32-bit.  ***Will require a reboot***

3. From the 2008 server, run the following command: <installdirectory>:\Program Files\Microsoft Data Protection Manager\dpm\bin\ SetDpmServer.exe –dpmServerName <servername> where <servername> is equal to your DPM server.

4. On the DPM server, use the DPM Management Shell and type Attach-ProductionServer.ps1 which will run a script where you can manually add the server to DPM.  First it will ask for the DPM server, type that in and press enter.  Next type in the Server 2008 name and press enter followed by the correct credentials.

5. Verify your servers has been added to the DPM console.
