Fix deletion of RegisteredApplication RegValues
The Registry Values in all RegisteredApplication Keys get properly deleted now.
Also HKCU\Software\Forschungszentrum Juelich GmbH
is deleted if it only has one entry (which then is PeTrack
). If it has multiple entries, i.e. some other software was installed under the same registry key, only HKCU\Software\Forschungszentrum Juelich GmbH\PeTrack
gets deleted.
