It won't work on newer books. Kindle has a new DRM and if you try to install older versions of the kindle application you will get an error.

You need to download the books from the "Manage Your Content and Devices" page using the "Download & transfer via USB" link. Those still use the old DRM.

Unfortunately that option is not available for all ebooks.

That's a bummer. I haven't bought an ebook in a few months, had no idea.
