I haven't tested whether this is correct, but some online topics seem to indicate that Visual Studio license keys are stored in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\
<version number>\Registration\2000.0×0000\PIDKEY
Office keys should be stored in the registry locations below, which are scanned by default even if they are not in the list of scanned registry locations. If your Office keys are not detected after scanning, I assume they are not stored in the client machines' registries, which is not something we can fix. Not all Office keys are stored in the registry, as explained in
this article as well.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office (64-bit machines)
