For KFX format, you need Kindle for PC 1.26 or earlier. Alternately use one of the methods for avoiding KFX format. See this post for details: https://www.mobileread.com/forums/showthread.php?t=283371

@ElleKayEm Can we remove DRM by Voucher File, I want to remove drm, in kindle content folder there present folder of ebook that contains voucher file, MD file, also azw file. The same log generated on my pc as in this issue, in this log

DeDRM v7.2.1: Failed to decrypt with error: The .kfx DRMION file cannot be decrypted by itself. A .kfx-zip archive containing a DRM voucher is required.

Read this log in last I said DRM voucher is required so it is present in my kindle contents folder So can we remove DRM by using that voucher file

@Cgpachore That's KFX format. You will need the KFX Input plugin in addition to DeDRM. And as I said above, Kindle for PC/Mac 1.26 or earlier. Or see the link above for methods to avoid the KFX format. If the book is only available in KFX and requires the latest Kindle app, then it can't be decrypted at this time.
