Installed DeDRM 7.2.1.
Not smart enough to know how to install the DeDRM tools master from this repo.
From Calibre's UI Plugin installer it kept looking for .zip but then didn't like DeDRM_tools-master.zip, saying:
"calibre, version 6.20.0
ERROR: Unhandled exception: InvalidPlugin:The plugin in 'K:\Downloads\DeDRM_tools-master.zip' is invalid. It does not contain a top-level init.py file

So I copied the DeDRM_plugin folder to the C:\Program files\Calibre2\app\plugins folder. That's prob not right.

I did install the KFX Input and KFX Output plugins, but still not getting it to convert to PDF.
My only Kindle "device" is the Win desktop app, so no SN (that I can find).

Anyone know how to get this to work?

Thank you.

First, you need DeDRM 10.0.3 for calibre 6. Download DeDRM_tools_10.0.3.zip from here:
https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3

Unzip DeDRM_tools_10.0.3.zip and load DeDRM_plugin.zip into calibre.

See this post for workarounds to get decryptable Amazon books: https://www.mobileread.com/forums/showthread.php?t=283371

Thank you for the 10.0.3 link. Got that installed.
I tried some of the applicable things on the mobileread thread.
Searched all over C: but can't find render-test.exe (below).
Where else might it (or something like it) be hiding?

Cut and paste the appropriate command for your operating system to disable the renderer-test program.
PC:
ren %localappdata%\Amazon\Kindle\application\renderer-test.exe renderer-test.xxx
Mac:
chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test
This prevents the renderer-test program from executing, blocking the use of KFX.

PC Note: The renderer-test program may be in a different location in some Kindle for PC installations. If the rename command fails look in other folders, such as C:\Program Files\Amazon\Kindle.
