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.

Running SophosZap (uninstaller tool)
