DRM removal happens when you first add the book to calibre. We'll need to see an import log to figure out if that's the issue.

The key that DeDRM is finding isn't the right one for this book. Was it downloaded with the current installation of Kindle for PC on the same machine and user as calibre with DeDRM?

[Ravikshukla]

yes it was downloaded with the same installation, but I had also downloaded the sample book previously, is that what is causing the problem? How do I solve the issue?

[ElleKayEm]

No, downloading a sample shouldn't be a problem. You should be able to decrypt the sample or the full book. Maybe the key DeDRM is finding is from a previous installation? Is this a purchased book or a rental?

[Ravikshukla]

I have purchased this book. I had downloaded the sample book before purchasing the book though.

[ElleKayEm]

I'd try removing the book from Kindle for PC and redownloading. Remove previous copy and add this new copy to calibre.

If that doesn't do it, the next step is to do a complete uninstall and reinstall of Kindle for PC. See these instructions:

https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#i-have-installed-the-calibre-plugin-and-the-book-is-not-already-in-calibre-but-the-drm-does-not-get-removed-it-is-a-kindle-book

Looks like you have Kindle for PC version 1.17 installed now. If you don't still have the setup file for that, scroll down on the first post here for info on "Obtaining and verifying Kindle for PC/Mac software":
