Hello Steve,
Here is how to manually fix the installer issue in Windows 10.
1. First you need to locate the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion
\Uninstall .
More info.
2. Find Remote Utilities GUID under that key node and delete the RU GUID. The list of RU GUIDs for all versions is available
here. You probably need the one for version 5.6.0.6.
Hope that helps.
