(There isn't a DeDRM_calibre_plugin folder anymore.) With either one, unzip the main file and load DeDRM_plugin.zip into calibre. If you're using calibre 4.23 or earlier, use DeDRM 6.8.1: If you're using calibre 5.x, the current DeDRM is 7.1.0: Otherwise you may run into memory issues decrypting larger files. I recommend using 64-bit calibre if possible. But if you disable KFX downloads, you can decrypt books from even the latest version.
