I am on Windows 10 and I am having difficulties in removing the DRM from Kindle books with Calibre, even though I have the DeDRM and KFX plugins on Calibre
In addition, I have followed the online instructions , namely :
1. deregistered the latest existing Kindle Reader app
2. install and re-register the old one ( v. 1.24.3 (51068) )

My books are currently on the Cloud. They belong to the same collection ( Amazon Delphi Classics) in the Kindle format. I had bought them two years ago and already removed the DRM from them on Calibre, but I have to redo it now because I had to reformat the drive. This time it doesn’t work.



By clicking on DOWNLOAD, the Cloud book(s) gets downloaded to the My KindleContent directory with various code sequences beginning with B.......
I then I drag these books into Calibre . Most of them show in the AZW format, some in the AZW3, some MOBI and some in the KFX-ZIP.

For some reasons Calibre cannot remove the DRM , with the exception of one AZW3 file. As I said, there is nothing wrong with these books, because I had already removed the DRM before with Calibre when I bought them originally.

Also, when I try to log-in to Re-register the older downgraded Kindle Reader app, I am unable to type in my e-mail addreas , PW and other info in the approrite boxes: the screen flickers all the time and I cannot place the cursor in the box. It happens only here. Maybe the problem is that the system fails to register the old Kindle reader App.just installed
I wonder if you can help.

THanks
