Generating eBooks for Kindle devices requires a free utility called KindleGen. Vellum uses this program to create the final, Kindle-ready .mobi files that you can load on your Kindle device or upload to Amazon. Even if you’ve previously installed KindleGen on your computer, it’s important to follow these instructions so that Vellum will always be able to locate this utility.
Until you download and install KindleGen, you will see a message like the following before generating eBooks for Kindle:
After you press the Install button in the Generate sheet, Vellum shows you the following dialog:
Installing KindleGen: Mac App Store
The Mac App Store version of Vellum, no longer available for sale, requires a more involved process to install KindleGen.
If, after pressing the Install button, you see a dialog is different from the one above, you are likely using the Mac App Store version of Vellum.
Rather than following the more complicated process to install KindleGen for this version, we strongly recommend migrating to the Direct version of Vellum.
