Help, please. For a long time I've been using Calibre 3.44 on Windows 7, to convert my Kindle purchases to epub format so that I can enjoy reading them in the "Moonreader Pro" app on my phone.

Today I bought a new Kindle book, opened "Kindle for PC" on my computer, updated the library, the book appeared in the list, but I couldn't download it. To download the recently published Kindle book "Kindle for PC" advised that I needed to update to the latest version of "Kindle for PC" for Windows 8 and 10, but I and my computer couldn't handle either of them.

I understand that this is my first encounter with Kindle's "new" KFX format.

I have read that I must also update Calibre to version 5.00 or higher to be able to install the KFX plugin, but I suspect that Calibre 5.00 or higher won't operate on "Windows 7".

So, please, is there a workaround, so that I can convert Kindle KFX books on my Windows 7 computer?
