Thanks, ProfC13

Have you read the section "Recent Changes to Kindle for PC/Kindle for Mac" at the FAQ URL listed in the error messages? Not KFX files can be decrypted currently.

What version of Kindle For PC are you using to get the ebook from Amazon?

Also do you have the KFX Input plugin installed in Calibre as you are trying to decrypt a KFX file so need to have software to handle them?

For KFX files, you'll need to install the KFX Input plugin and use Kindle for PC 1.26 or earlier. Alternatively, disable KFX downloads or use Kindle for PC 1.17 (which doesn't permit KFX downloads.) See this post for details: https://www.mobileread.com/forums/showthread.php?t=283371

Thanks! gone back to kindle 1.17 (version bevor was 1.30, disable render-test.exe won't work), deleted hole contents and started from scratch. For now it works...

[ElleKayEm]

Yes, renaming redenderer-test only works in Kindle for PC 1.24 and earlier. There's another way to disable KFX in later versions, but I prefer sticking with 1.17 myself.

If you're all set, you can close the issue.
