Agent update failed

After installing the new Hotfix rollup package for DPM 2007 (KB979970) you have to update the agents. In my case this went fine for almost all agents.
Only the agents on the SharePoint servers had a nasty issue.

The (push) upgrade failed with the following error.


Agent Operation failed (ID 370)
The agent operation fauled because an error occurred wile running the installation program on <compter name> (ID 313). Details: The installation source for the product is not available. Verify that the source exits anf that you can access it (ox8007064c)
The local agent installation shows a same kind of error:

DPMAgentInstaller failed with errorcode =8007064c, error says: The installation source for this product is not available.  Verify that the source exists and that you can access it.

Check log files in [WINDIR]Temp\MSDPM*.LOG
Press Enter key to close the window
For this error messages it is not clear which installation files are missing.

The log MSDPMAgentPatchInstall.LOG (windir\temp) shows in more detail which files are required.

The agent upgrade requires the file dpmra.msi from the directory C:\WINDOWS\Microsoft Data Protection Manager\DPM\Agents\RA\2.0.8844.0\.
This is actually the installation file from the current agent version (2.0.8844). The issue is that this directory does not exist on the server and the installation files are not in any other directory on the server.

Solution (workaround)
The only way I could get the required source files was installing the old agents files (2.0.8864) to (a temporary)machine. The source is available on the DPM server (\\dpmservername\c$\Program Files\Microsoft DPM\DPM\Agents\RA\2.0.8844.0).
When installing the agent a temporary directory is created on the machine (like: 4cf3806aac3ed28e02810670b5) copy during installation the files from this directory to temp directory.
Now you have a valid copy of the installation files. Copy these installations files to the server that fails to upgrade the agent (directory C:\WINDOWS\Microsoft Data Protection Manager\DPM\Agents\RA\2.0.8844.0\) and retry the agent upgrade

Not a very nice solution, but at least it worked for me…

  1. Just stumbled on this while looking up info for the error, and it's for 2007 just trying to update the agent to SP1. I'm a bit confused about how to get the files during installation, where they live during the installation. C:\Windows\Temp?

    Let me see if I've got this.

    1) I run an installation on a temp machine, my workstation for instance.
    2) I grab the contents of that directory and copy it to a temp folder.
    3) I copy those files then back to the agent machine into C:\WINDOWS\Microsoft Data Protection Manager\DPM\Agents\RA\2.0.8844.0\
    4) Go back to the server and run the upgrade.


    1) Where is the temp installation directory created on the agent machine?
    2) There is nothing in my RA folder and the numbers I have currently don't match. The AC folder has 2.0.5820.0, if I just make a folder called 2.0.8844.0 is that going to mess things up?

    Thank you.
