The simplest option for removing DRM: Calibre Plugins

Re: The simplest option for removing DRM: Calibre Plugins

 

Try adding a plugin from the plugins folder, not a zip of the stand-alone DeDRM tool.

Re: The simplest option for removing DRM: Calibre Plugins

 

Run Calibre. Click Preferences. Click Plug-ins.
Click on the large “Add a new plugin” button
Navigate to the tools folder unzipped in step 2
Open the Calibre_Plugins folder
Select one of the zip files in that folder


Lod plug in from file
Calibre 0.8.8 cannot see zips in folder.

As usual, just posting about the problem essentially fixed it (within minutes of my posting, literally). :p

Turns out that I needed an older version of Kindle4PC. Amazon's latest version was the source of the problem. Installing 1.4.1 and redownloading the eBook through the older version of Kindle4PC gave me a version that Calibre was able to work with.

Thanks a bunch for this info. All my, originally Kindle, books are now readable from my iBooks App on my iPad. Love it.

Hi,
I am trying to remove the DRM from a pdf that does open in Adobe Digital Editions. It is a library book. I installed the tools, here are the error messages I get:

Admittedly this is all a little over my head. Any help would be appreciated.

Thanks!

OK, nevermind, I guess it is because it's a library book. I thought I used to be able to fix these on my old computer, but maybe I am just mis-remembering.
