Does anyone own a unique, valuable piece of Adobe Acrobat DC product?

Previously, when installing Adobe Acrobat DC, 'HKLM\SOFTWARE|Adobe\Acrobat Distiller\DC' was created.
When installing Adobe Acrobat Reader DC, the path 'HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Adobe Acrobat\DC\RDCNotifiationAppx' was created.

However, at some point, even though Adobe Acrobat Reader DC was installed, a registry for the Adobe Acrobat DC product was created.

This is a huge problem, since I was looking at the registry to see what products were installed.

Can someone please tell me which registry only exists when I install Adobe Acrobat DC?

Also, the registry I found is 'HKLM\SOFTWARE\Adobe\Adobe Acrobat\DC\RDCNotificationAppx (AppName: ADCNotificationClient.appx)'.

Is this registry created identically in all versions of Adobe Acrobat DC?
