Convert the book with Calibre to an e-book format that LingQ can import, for example PDF (you can find the converted, DRM-free e-book in your Calibre library on your hard disk: ).The default mode is to remove the Kindle book's DRM immediately (in other words, you don't have to do anything!). Add a Kindle e-book that you downloaded in step 2 to Calibre.
Start Calibre and add the plugin via "Preferences" by navigating to the folder "DeDRM_tools_7.1.0" and choosing the zip file "DeDRM_plugin" ( ) - see PPPS for "details". Unzip the DeDRM plugin to a folder, for example: "DeDRM_tools_7.1.0". Download both Calibre and the plugin DeDRM (the newest versions should work just fine). Install and open the Kindle app, click on the e-books in your Kindle library that you want to convert and download them to your hard disk (the default path is: C:\Users\YOURUSERNAME\Documents\MYKindleContent\). Here you can download the Kindle for PC v 1.17 app: ( Note: Disable the option "Install available updates automatically without asking" under "Tools - Options - General", otherwise Kindle version 1.17 will be replaced by a newer one!).
It´s crucial to use the older Kindle version 1.17, not a newer one! Then the conversion process to a DRM-free format should work just fine for many, but perhaps not for all Kindle e-books.So here is the procedure for creating Kindle-DRM-free e-books for a Win 10 system in a bit more detail: Since I had to configure a new Win 10 PC yesterday, I also had to install some software like Calibre, Kindle for PC, etc.
