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

Keiron Crawford

 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.
