If you have other DRMed ebooks, you will need to enter extra configuration information.

On Linux, keys for Kindle for PC and Adobe Digital Editions need to be generated separately (see the Linux section below) If all your DRMed ebooks can be opened and read in Kindle for Mac/PC and/or Adobe Digital Editions on the same computer on which you are running calibre, you do not need to do any configuration of this plugin. On Windows and Mac, the keys for ebooks downloaded for Kindle for Mac/PC and Adobe Digital Editions are automatically generated. However, you should also delete any older DeDRM plugins, as this DeDRM plugin replaces the five older plugins: Kindle and Mobipocket DeDRM (K4MobiDeDRM), Ignoble Epub DeDRM (ignobleepub), Inept Epub DeDRM (ineptepub), Inept PDF DeDRM (ineptepub) and eReader PDB 2 PML (eReaderPDB2PML). You have obviously managed to install the plugin, as otherwise you wouldn’t be reading this help file.

If you already have DRMed ebooks in your calibre library, you will need to remove them and import them again. This plugin removes DRM from ebooks when they are imported into calibre. DeDRM Plugin Configuration DeDRM Plugin (v6.0.9)
