Agent Upgrade

Manually Uninstall & reinstall Desktop Central Agent in client computers - "Fatal Error"

Problem

Whenever there is a change in the Agent Version, the Desktop Central Agent will automatically get upgraded during the 90 minutes refresh cycle. If you are trying to upgrade the Desktop Central Agents manually in client machines instead of waiting for the automatic upgrade, you need to first uninstall the existing agents to proceed with Agent Upgrade. However when you do this you find that agent uninstallation fails with error message - "Fatal Error".

Cause

You may encounter this error due to one or more of the following reasons:

  1. The uninstallation component for the Desktop Central agent is missing i.e. dcagent.dll is missing under programfiles\desktopcentral_agent
  2. Registry got tampered i.e. Registry entries under HKEY_LOCAL_MACHINE\Software\Desktopcentral\DCAgent\ might be corrupted / deleted

Resolution
