You have Adobe Digital Editions used to download the book on the same machine and user as calibre with DeDRM?

[aldval59]

In the past some have had luck with deauthorizing and reauthorizing ADE. On this page scroll down to TROUBLESHOOTING REAUTHORIZATION AND DEAUTHORIZATION ISSUES ON WINDOWS.

Or you might look at the DeACSM plugin which allows you to skip using ADE: https://www.mobileread.com/forums/showthread.php?t=341975

[aldval59]

thank you ElleKay. I tried to deauthorize and reauthorize my ADE id following the instructions of the suggested page. The deauthorization was OK but when I tried to delete the Adobe adept registry key I obtained a message that was impossible to delete all specified values, then I have reauthorized my ADE id but nothing has changed. In the Adobe adept registry key I noticed that in data section there is 'value not setted' 'valore non impostato' in italian language. Hereafter I tried to paste the image of the registry key but I don't know if you can see the image file.

[ElleKayEm]

That is what I see there too on my system and things are working for me. I do notice that it looks like you have or had different installations of ADE: there are Adobe Digital Editions, Adobe Digital Editions 4.5, and Digital Editions folders. I have only ever had ADE 2.0.1 on my computer and I only see the Digital Editions folder. It could be that DeDRM is picking up info from the wrong version. I wouldn't mess with deleting anything else in the registry. But if you do have both ADE 4.5 and a previous version installed currently, I'd try de-authorizing and uninstalling the one that you did NOT use to download the book.

Again using the DeACSM plugin and not messing with ADE at all might be a workaround. I haven't tried that myself at all since ADE has continued to work for me.

[aldval59]

I have added DeACSM plugin in Calibre and I have loaded the ebook, when I double-click to open the ebook ADE starts and open the ebook correctly (but I haven't had any problem to open the ebook in ADE before), but I suppose tha the ACSM file that I have in Calibre cannot be loaded in my Pocket Book ereader (and I cannot convert it in any other format). I'm using 4.5.11 ADE version but I cannot see any other ADE version on my computer. Thanks a lot again for your support.

[ElleKayEm]

No, acsm is not a book. But the DeACSM plugin should download the epub into calibre.

[aldval59]

Not for me, in Calibre I see an ACSM file with the name ACSM, the same I see in the folder where the ebook has been downloaded.

Haven't used it myself, as I said, but that's its entire purpose -- to replace downloading the epub with ADE.

[MTOakey]

Windows 11, all App's are the most updated versions, including Kindle for PC. Just installed AFTER purchasing an Amazon Kindle ebook. Book shows up in KforPC. Set calibre "default conversion" to PDF. Selected the .azw file ... Had Terminal open and ran Calibre in Debug mode... DID NOT DeDRM.

Any help would be greatly appreciated.

@MTOakey Update to DeDRM 10.0.3: https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3

But you will need an older version of Kindle for PC to get this book in a format that can be decrypted. See this post: https://www.mobileread.com/forums/showthread.php?t=283371

Hello, probably the problem is that I have not the ADE key configured in Calibre. Somebody could suggest me where I can find the ADE key ? Thanks.

[ElleKayEm]

DeDRM will automatically retrieve the key from ADE installed on the same machine and user as calibre when you add your book.

[aldval59]

It should be like you wrote but the error log you can find hereafter shows that it doesn't work. P.S. Calibre and ADE are on the same machine.

So I'm trying to add the ADE key in Calibre configuration, but I don't know how and where retrieve it.

[ElleKayEm]

That installation of ADE is the one you used to download the epub? You can read the epub in ADE?

[aldval59]

Yes I can read the ebook in ADE.

[aldval59]

I have a problem when I import the ebook in Calibre because the DRM is not removed.

[ElleKayEm]

I don't know why it isn't working then. Adding a book which was downloaded with the current installation of ADE is how the correct key is retrieved.

[aldval59]

So you don't know how to add the ADE key by yourself. Many thanks anyway.

[ElleKayEm]

You can add the key by clicking the green plus sign in your screen shot. But that won't work in your case. The only other way would be to save a key from another setup (which used the same Adobe ID) and use the import existing keyfiles button.

[ElleKayEm]

Maybe try a fresh setup and a fresh download of the book.

[aldval59]

Many thanks, I will try following your suggestions.
