When installing Backup Exec Media Server or Remote Agent a Fatal Error may appear during install.

Note: Backup Exec installer now requires .NET 2.0 for installation of Backup Exec Media Server or Remote Agent.


The install failed with an unexpected error: Configuration system failed to initialize.


Possible corruption in .NET 2.0 install.


If an error occurs during install of Backup Exec Media server .NET 2.0 may need to have one or both of the following competed.
  • Run a Repair install of .Net 2.0.
  • Uninstall .NET 2.0 and Reinstall.

Note: If the .NET 2.0 is uninstalled for a Media Server Installation the Backup Exec installer will install .NET 2.0 during the pre install function.

Please see the below Article from Microsoft on how to Repair .NET 2.0

When the command on the above Microsoft KB article is used, it might fail to repair the .NET framework with error: Internal Error 2908
For this, browse to the C\Windows\System32 and look for a file: mscoree.dll
Rename the file to mscoree.dll.old and then try to run the command again to repair .NET 2.0.
Once the repair is complete, try to install the remote agent again.

 If .NET cannot be repaired or reinstalled, either due to corruption or because it is embedded into the operating system, Microsoft will need to be contacted for further assistance. In some of these cases, it has been determined that a reinstall of the operating system is the only resolution to the .NET issue.
