Two essential files used by the Sophos Remote Management System component cannot be located by the installer.

What To Do

  1. At a computer that is successfully managed from the Enterprise Console, go to:
    C:\Program Files\Sophos\Remote Management System\
  2. In this folder are two files:
    • mrinit.conf
    • cac.pem
  3. Copy these two files across to the computer which has the error, and place them in the same folder location:
    C:\Program Files\Sophos\Remote Management System
    If the folder is not listed, you should create it.
  4. Once done, right-click on the Sophos shield icon in the system tray, and select 'Update now'.
  5. After the update has completed check whether the Remote Management System has been installed.

If the problem persists, refer to article 36097 for troubleshooting installation errors using Microsoft Installer log files..
