I’ve fully unzipped the tools archive, but I can’t find the calibre plugin when I try to add them to calibre. You must unzip the archive, and install the calibre plugin from a folder called “DeDRM_calibre_plugin” in the unzipped archive. It is a collection of various DRM removal tools which includes calibre plugin. The tools archive is not a calibre plugin. You might be trying to add the tools archive. I am trying to install the calibre plugin, but calibre keeps on saying that the plugin is invalid. Support for removing DRM from rented or library ebooks is not provided. Getting and Using the Tools I can’t get the tools to work on my rented or library ebooks. This post has links to downloading a zip archive of all the tools, as well as a comments area for asking questions.
