Sophos Enterprise Console pre-requisites states that Sophos Update Manager is already installed when it has been removed. You see the 'System Property Checks' error:
Sophos Update Manager is already installed. Please uninstall it before continuing.
First seen in Enterprise Console 5.1.0
After uninstalling Sophos Update Manager sometimes an 'Upgrade Code' is left behind in the Windows registry. This Upgrade Code is detected by the Console installer to see if Sophos Update Manager is still installed.
The steps below involve using Microsoft's Process Monitor tool to capture the location of the registry key being detected by the installer and then delete that key. These steps assume your are familiar with Process Monitor and have downloaded a copy already. For more information on Process Monitor see article 119038. Before editing the Windows registry see article 10388.
