How was this downloaded? DeDRM doesn't currently work with Kindle for Mac. If this is from Kindle for PC, you'll need to use calibre/DeDRM/KFX Input on the machine it was downloaded on in order retrieve the key for that.

I've run into nearly this exact error listing on my Mac. In my case I entered the serial number for my Kindle Scribe and downloaded the .kfx directly from the Scribe onto my Mac to be processed. It looks like it tried to run my serial number as a key, failed, looked for Kindle for Mac to grab a key from it, also failed, and then ended.

I know DeDRM is installed correctly and working, as I previously downloaded a batch of books and converted them from .azw3 successfully. It's just choking on .kfx for some reason.

@ElleKayEm

You have KFX Input installed?

@shahmatdotnet
Copy link

Yes, KFX Input is installed and enabled and the "Allow import of KFX format books from Kindles" setting is checked (although I also tried without checking that once and it still didn't work). I also get the lines above about Gather KFX-ZIP running so I'm pretty sure it's using KFX Input to try to read the files.

@ElleKayEm
Copy link

You're adding the books from D:\documents\Downloads\Items01 (if D: is your Kindle)
filename should be in the form of book_title_ASIN.kfx

Leave everything in its original folder structure.

Amazon made me install a utility that just opens up a file manager to the Kindle storage so I couldn't get calibre to reference that path directly, and I've never been able to get calibre to connect directly to my Scribe as a device. However, I did notice that each book had a matching .sdr folder, so I copied both the .sdr folder and the .kfx file to my Mac desktop and ran calibre on that. It won't display the KFX format for some reason (not sure if the reader just doesn't know how to render it or if I need to tweak the KFX Input plugin some more) but I can convert to epub or mobi without problems.

Thank you for the advice!

Oh, sorry, I was looking at my Oasis plugged into a Windows machine and forgetting about the Scribe using MTP. To read KFX in the calibre ebook viewer, go to Preferences > Behavior and check KFX in the right column of formats to use the internal viewer.

I'm having the same problem; the files start off as .azw files downloading using the Windows 10 Kindle App (ver 2.4.0 70904). Drag and drop into Calibre and they get unpacked as .KFX-ZIP, I have DeDRM 10.0.3 and KFX Input 2.19.0 installed, enabled, and configured per instructions and showing up in the file types, but attempting to open or convert the files gives the DRM message. .azw files that unpack into MOBI with DRM are able to remove DRM and convert just fine; so it's something specific to the KFX-ZIP :\

Having the same issues here. I have Kfx Input and DeDRM plugins installed. I added my Paperwhite serial number to the DeDRM plugin configuration, but the books keep being imported as KFX-ZIP in my Calibre library :(
