Download and install the latest version of Calibre. Guides will tell you, you need to downgrade or install an earlier version of Calibre. Go Tools -> Options -> Uncheck Automatically update on start. You also need to prevent the 'Kindle for PC' app from updating once you close it. Most of these don't work anymore, but some of them still do. There is a drop-down menu at the bottom of the screen that says 'Default'. Once you try to open 'Kindle for PC' you will be stuck at a constantly reloading sign-in screen, because the server is refusing to authenticate the outdated client. This is the latest version that will download your ebook, with the older DRM. You need an earlier version of 'Kindle for PC', 8.

I think this went unnoticed by the people making these guides, which are full of straight up wrong information on how to strip the DRM from and convert your Kindle library, when you don't own a Kindle.

Hardware + serial number will always work, but getting DeDRM to actually decrypt the NEW DRM is impossible.

This is because Amazon changed how their DRM works. So, most of the guides, I'm sure still work if you have a hardware Kindle and your serial number.except I'm not in that group, and the guides don't work if you are trying to follow the 'Kindle for PC' guide. Therefore I begin my investigation into how to strip the DRM so I can convert my library. I read this content on the PC, or through the Kindle app on my phone, but decided I would drop a little money on something better suited.except I bought a device, a Kobo to be exact, that doesn't support this DRM. I suspect my foray into ereaders is very late, yet I have a ton of digital ebook content from many stores.
