When your ebooks have DRM you are unable to convert the ebook from one format to another (e.g. Kindle KF8 to Kobo ePub), so you are restricted in the range of ebook stores you can use. DRM also allows publishers to restrict what you can do with the ebook you've bought, e.g. preventing the use of text-to-speech software. Longer term, you can never be sure that you'll be able to come back and re-read your ebooks if they have DRM, even if you save back-up copies.

You will need to go to the preferences and uncheck the auto update checkbox. Then download and install 1.17 over the top of the newer installation. You'll also need to delete the KFX folders from your My Kindle Content folder. You may also need to take further action to prevent an auto update. The simplest wayis to find the 'updates' folder and replace it with a file. See [this thread] (http://www.mobileread.com/forums/showthread.php?t=283371) at MobileRead for a Script to do this on a PC. On a Mac you can find the folder at ~/Library/Application Support/Kindle/ just delete the folder 'updates' and save a blank text file called 'updates' in its place.

Another possible solution is to use 1.19 or later, but disable KFX by renaming or disabling a necessary component of the application. This may or may not work on versions after 1.25. In a command window, enter the following commands when Kindle for PC/Mac is not running:

After restarting the Kindle program any books previously downloaded in KFX format will no longer open. You will need to remove them from your device and re-download them. All future downloads will use the older Kindle formats instead of KFX although they will continue to be placed in one individual subdirectory per book. Note that books soudl be downoad by right-click and 'Download', not by just opening the book. Recent (1.25+) versions of Kindle for Mac/PC may convert KF8 files to a new format that is not supported by these tools when the book is opened for reading.

#### Decrypting KFX

Thanks to work by several people, the tools can now decrypt KFX format ebooks from Kindle for Mac/PC. In addition to the DeDRM plugin, calibre users will also need to install jhowell's KFX Input plugin which is available through the standard plugin menu in calibre, or directly from [his plugin thread](https://www.mobileread.com/forums/showthread.php?t=291290) on Mobileread.

## Where can I get the latest version of these free DRM removal tools?
|
||||
Right here at github. Just go to the [releases page](https://github.com/noDRM/DeDRM_tools/releases) and download the latest zip archive of the tools, named `DeDRM\_tools\_X.X.X.zip`, where X.X.X is the version number. You do not need to download the source code archive. This will get you the forked version by noDRM. If you want to download the original version by Apprentice Harper, go to [this page](https://github.com/noDRM/DeDRM_tools/releases) instead.

## I've downloaded the tools archive. Now what?
|
||||
First, unzip the archive. You should now have a DeDRM folder containing several other folders and a `ReadMe_Overview.txt` file. Please read the `ReadMe_Overview.txt` file! That will explain what the folders are, and you'll be able to work out which of the tools you need.

|
||||
|

## That's a big complicated ReadMe file! Isn't there a quick guide?
|
||||
Install calibre. Install the DeDRM\_plugin in calibre. Install the Obok\_plugin in calibre. Restart calibre. In the DeDRM_plugin customisation dialog add in any E-Ink Kindle serial numbers. Remember that the plugin only tries to remove DRM when ebooks are imported.

### I am trying to install the calibre plugin, but calibre says "ERROR: Unhandled exception: InvalidPlugin: The plugin in u’[path]DeDRM\_tools\_6.8.0.zip’ is invalid. It does not contain a top-level \_\_init\_\_.py file"
|
||||
You are trying to add the tools archive (e.g. `DeDRM_tools_6.8.0.zip`) instead of the plugin. The tools archive is not the plugin. It is a collection of DRM removal tools which includes the plugin. You must unzip the archive, and install the calibre plugin `DeDRM_plugin.zip` from a folder called `DeDRM_calibre_plugin` in the unzipped archive.

You are trying to add the tools archive (e.g. `DeDRM_tools_10.0.2.zip`) instead of the plugin. The tools archive is not the plugin. It is a collection of DRM removal tools which includes the plugin. You must unzip the archive, and install the calibre plugin `DeDRM_plugin.zip` from inside the unzipped archive.
|
||||
|
||||
### I’ve unzipped the tools archive, but I can’t find the calibre plugin when I try to add them to calibre. I use Windows.
|
||||
You should select the zip file that is in the `DeDRM_calibre_plugin` folder, not any files inside the plugin’s zip archive. Make sure you are selecting from the folder that you created when you unzipped the tools archive and not selecting a file inside the still-zipped tools archive.

## My Kindle book has imported and the DRM has been removed, but all the pictures are gone.

Most likely, this is a book downloaded from Amazon directly to an eInk Kindle (e.g. Paperwhite). Unfortunately, the pictures are probably in a `.azw6` file that the tools don't understand. You must download the book manually from Amazon's web site "For transfer via USB" to your Kindle. When you download the eBook in this manner, Amazon will package the pictures in the with text in a single file that the tools will be able to import successfully.
