DRM Still Remains

[Andrius2015]

I apologize if it has been posted before (as I have limited knowledge of the intricacies of this process), however, I am wondering if I am doing something wrong. I am using Calibre 5.10 and have installed (successfully) DRM 7.0.2 and also tried with 7.0.3, but still, the DRM remains. I have also tried to use earlier versions of calibre and accordingly, the DRM - but I have the same error.

After conversion, the DRM still remains and the debug content is below: Thanks for any assist!

calibre.ebooks.DRMError: The book

[ElleKayEm]

I'm not seeing DeDRM even trying to do anything here. If you're using beta DeDRM, might as well use the latest 7.0.3. What type of book is it? And how did you download it? We might be able to tell more with an import log: https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#i-cannot-solve-my-problem-with-the-dedrm-plugin-and-now-i-need-to-post-a-log-how-do-i-do-that

Interesting.... Thanks for the feedback. The book is from Amazon downloaded to kindle PC (v1.17 build 44183). I tried using 7.0.3 but it just gives me an error that the book is protected by DMR. I have had a functional calibre and DMR set up before on my old PC, and then had to get rid of it, so was trying to set up with a new one only to get this problem.

Should work if you downloaded the books with the installation of Kindle for PC currently on the same machine and user as calibre with DeDRM. Post an import log, and we'll figure it out.

Thank you so much for telling me this! I didn't know that the kindle content has to be unlocked from the same user as the one where it was bought, for the process to work. I was trying to carry out the process on another machine (because I had PC issues). I now repeated all the processes on a single machine and it all worked. Thank you very much!!!

Why is this the case, that all the processes need to be on one machine?

[ElleKayEm]

Each installation of the Kindle app has a unique key, even when they are logged into the same account. DeDRM needs to be able to retrieve that key in order to be able to unlock the books downloaded with it.
