Why can’t I install/uninstall Sophos Home?:

You may encounter any of the following issues with Sophos Home:

  • Continuously getting a message to restart the computer to uninstall or reinstall Sophos Home.
  • You receive uninstallation/installation failed errors.
  • You are unable to reinstall Sophos Home due to error messages.

These issues  usually happen due to corrupted files or remnants from previous installations of Sophos Home or other Sophos versions, especially when using a third-party uninstaller that may delete components that are required to properly uninstall Sophos.
The problems can also occur when another security software is installed, or if the operating system files are corrupted/permissions are not properly set.

Unable to uninstall – Running SophosZap (uninstaller tool)

SophosZap is a last resort command line clean up tool focused on uninstalling Sophos Endpoint products to revert a machine to a clean state.
Before you run this tool, we strongly recommend that you use the standard product uninstaller first. Only use SophosZap when all other uninstall options have failed, as SophosZap uses heuristics trying to identify Sophos components on potentially partial information and that carries additional risks.
