Failed to install Sophos Anti-Virus for Windows: uninstalling an older product failed.

 Endpoint half un-insatlled... now I am just stuck in a loop...

The machine thinks nothing is there...

I can run the Installer again, it performs the 'Pre-Installation' and starts the Download and fails after 20 mins

How does one Remove Sophos Endpoint so I can re-install 

I have tried to stop what services are left available and REG Setting for Tamper Protection... still get no where

Sophos Central, Win10 Any help is greatly appreciated

 

Cheers

  • Hi  

    If there are any components left from the older installer, you may check below registry and see if there are any leftovers keys for Sophos Anti-virus or. Please take reg backup before making any changes. 

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
    ​HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes
    HKEY_CLASSES_ROOT\Installer\UpgradeCodes\
    HKEY_CLASSES_ROOT\Installer\Products\  

    If you can provide installer logs from the temp folder, I can check about the component which is failing to get uninstalled.
