Mr. Murphy,
Thank you for your reply, but the software is for free. But I have started the Adobe Digital Edition again this afternoon and I saw now the Kobo ereader stated in the left colon and I was able (with assistance of a dictionairy) to understand the instruction for loading my ereader.
But I have no idea how to put this result in my original question.
With sunny greetings
Wim van Broekhoven
