Kindle for PC/Mac is not installed (No keys for decrypting Kindle books)

If you don't have an E-Ink Kindle:

For removing DRM from your Kindle books, we need some "keys" to decrypt them. And the keys are generated once your purchased Kindle books are synced by Kindle for PC.

Therefore, even you can read the Kindle book on reader apps on your cellphones or tablets. We still recommend you sync them via Kindle for PC for a successful decryption. Here is the guide.

First of all, please make sure you are using the latest version of our program (Free Upgrade), here is the download links: https://www.epubor.com/software-upgrade-policy.html

1Download and authorize Kindle for PC/Mac with your Amazon ID

Download Kindle for PC/MAC:

Kindle for PC V1.17 Download Kindle for Mac V1.17 Download

2Launch Kindle for PC/Mac

Go to Kindle Library, double-click each item to download Kindle books to your computer. Make sure you can open and read them on your computer.
