Calibre DRM Removal Tools no longer work with Kindle ebooks ...

[sunni]

I was using the Calibre plugins from version 3.4 of the tools with an earlier version of Calibre... I think it was 0.8.3. Kindle for PC was/is version version 1.3.

Everything was working fine until recently, and I have no idea why the deDRM no longer works when I import .azw files I've purchased into Calibre.

I noticed that I had a second version of Kindle for PC listed on my device page on Amazon. I have no idea why I had that and deregistered the 2nd K4PC, but it didn't make a difference. I am wondering if that had a different PID that is now somehow attached to my books or registry but the plugin is missing it.

I uninstalled and reinstalled the specific plugin for Calibre, but it still had the previous PID and still doesn't work.

The only recent changes are that I bought a Kindle, and I just upgraded Calibre to 0.3.17.

I had not imported any books into Calibre for a while, so I'm not sure whether either of those changes are responsible for my plugins no longer working.

I added my Kindle serial number to the customization with a comma after the PID and no spaces. I also tried it with a comma but with the spaces the serial number normally includes... neither worked.

I deleted all my books from my Kindle Content folder and re-download one of my purchased books to test. It still doesn't work.

I was thinking of uninstalling K4PC and reinstalling my old 1.3 version (I still have the installer) but I am afraid the old PID and any other old information will be left behind and when I reinstall I will have the same problem.

I don't know anything about Python. I'm not even sure where the K4PC exe is located. (I only found an Amazon folder in roaming, but it was empty.)

I am so frustrated by this and don't really know enough to fix it.

If I completely uninstall Calibre and reinstall my old version, will it remove the information belonging to my plugins so that when I reinstall it they will check for the PID again?

Should I uninstall and reinstall K4PC also?

I wish I knew what broke my Calibre plugin(s).

I had the same problem, as did a friend of mine with a similar setup. After reading a lot of posts here, I first deleted all my downloaded books, uninstalled Kindle for PC and the Calibre Plug-ins (from Tools 4.0). I then installed Kindle for PC ver 1.4.1, and then downloaded the books from Amazon again. I then installed the plug-ins from Tools 4.6, and everything is working fine again. My Calibre version is 0.8.16, and as long as things are working, I'm not going to "upgrade" any of the elements mentioned above. It is my understanding from reading posts here that K4PC versions above 1.4.1 alter the book file a bit and sometimes prevent the plug-ins used with Calibre from working.
To find 1.4.1 I did a Google search and eventually found it.
Good luck.

Thank you so much for your repsonse!

It's good to know that deleting all the books and reinstalling everything fixed the problem for you.

So you didn't have to uninstall and then reinstall Calibre before reinstalling your tools and they reset with the new PID for the new version of K4PC?

For Calibre, I have 0.8.17 now but can rollback to 0.8.3 and I'm wondering if I should reinstall 0.8.3 or just keep the most recent version of Calibre. Does it make any difference regarding the plugins?

It's strange that I started having this problem even though I had K4PC version 1.3 installed which is before it started breaking the tools.

Hi,

They work. Even with the latest K4PC 1.7.X. You just need to use the very very latest versions of the DRM tools (today that is tools_v4.7) and if you use the calibre plugins from tools_v4.7, make sure you have removed all earlier versions of the plugins.

If you run into problems when using the very very latest tools, then let the people at ApprenticeAlf know so they can fix things if need be.

Thank you AAfan. Is it enough to uninstall the tools and then uninstall and reinstall Calibre... or are there any folders left behind that I have to delete before reinstalling?

Hi,

Uninstalling and reinstalling Calibre does not help. Go to Calibre's Preferences->Change Calibre Behavior -> Plugins and then look at the File Type plugins and hit the little triangle at the front. You should see a list of all File Type plugins installed. Highlight any you want to remove and hit the remove button (don't forget to hit Apply to make sure your changes hold). I would remove any and all K4Mobi*, K4Mac*, Mobi*, plugins you have and then install the very latest K4MobiDeDRM plugin version 3.7 (taken from Calibre_Plugins folder inside tools_v4.7).

You should then have the latest.

I used Revo Uninstaller to uninstall K4PC and Calibre and remove all the leftover files. I reinstalled the latest versions of everything and it's finally working again. Thanks for all the help!

Notifying calibre of the change

File is now imported as a TPZ file in Calibre. Attempt to convert TPZ file results in the following error within Calibre:

calibre, version 0.8.27
WARNING: Could not convert some books: Could not convert 1 of 1 books, because no suitable source format was found.

Isn't K4PC supposed to be able to de-DRM TPZ files?

Tried loading older version of Calibre and Tools 4.6
Attempted same process as above on another PC running XP.
All other K4PC books in my collection seem to convert fine (XML and MOBI books).
Any suggestions here?
