KFX Conversion failed (but only for some books?)

[ghost]

I'm on a Surface Pro 4 with Windows 10 attempting to convert KFX files from a Kindle/Amazon purchase to EPUB files to bring into a Kobo account (both on desktop). I have 40 books and 38 worked fine. 2 are failing. I am using the latest version of DRM (6.7.0), 64bit version of Calibre (downloaded today) and version 1.24.3 of Kindle. Both books were legally purchased and downloaded via Amazon. I tried the troubleshooting tips on the ReadMe file but didn't work. I have also tried converting these books to other files but it doesn't work. Both books open fine in Kindle. I do not have a Kobo e-reader and my sisters Kindle e-reader is broken, so all of this is being done on desktop apps.

Error message: 'ERROR: KFX Conversion failed'

Any thoughts?

The most likely cause of those errors is using an outdated version of the KFX Input plugin.

If 38 of 40 were successful, then DeDRM (probably) isn't the issue. Are you using 64-bit calibre?

Yep I am, probably should have mentioned that

Is there a way to update that?

The latest version is 1.31.0. Calibre should offer the update to you at the bottom of the window. (Fixed wrong version.)

Okay, thank you! Good catch, the update wasn't installed. And it worked!! Thanks for that
