But with the help of the very friendly Adobe service consultant that I called shortly before 17:00 clock, I was able to perform to my satisfaction the process.
The phone number for support or customer service questions I found on their website at Contacts (069-500718 55).
After calling up the relevant links "portal for customer support from Adobe" I came to the registration page for the program. Then enter all data (PN number. Need not be entered) and the authorization number received from Amazon to enter, attach the required supporting documents and submit. You get a summary of the data and must confirm this again below. Then you get a case number and the matter is running! :-) The serial number then you get email sent and then register the product at last! :-)
I can only say to the program itself: I have worked with previous versions already and a big advantage is that the pictures themselves do not change, only the changes are displayed. The result can be exported and saved, the originals remain as they are of course.
The support for new raw formats is ensured by an update that you should install to usefully carry out the same.
I hope the tips will help a little further and to encourage people to use the program in spite of the somewhat cumbersome registration procedure.
