I tried to follow the latest instructions with updated apps, can't decrypt books.

I've got DeDRM v10.0.20 installed on calibre 9.8.0, KFXArchiver291.exe moved into c:\Users\luigi\AppData\Local\Amazon\Kindle\application. I have kfx input 2.31, I've recreated (I think?) a new keyfile, and now I entered the following command on cmd:

c:\Users\luigi\AppData\Local\Amazon\Kindle\application>KFXArchiver291.exe "C:\\Users\\luigi\\Documents\\My Kindle Content" "C:\Users\luigi\Documents\K4PC2.9.1" keyfile kindle_account.k4i
Scanning C:\\Users\\luigi\\Documents\\My Kindle Content for book folders
Kindle4PC appears to be installed globally, this is not tested and the utility might not work

Trying to open  NoteDocuments
Writing DSN and secrets into keyfile

c:\Users\luigi\AppData\Local\Amazon\Kindle\application>

The keyfile afaik is already in calibre, and i created a new folder ("K4PC2.9.1") where to store the downloaded ebooks. So, what went wrong?

EDIT: kindle_account.k4i doesn't appear in C:\Users\luigi\AppData\Local\Amazon\Kindle\application. So maybe it's this, how do i recreate it? I didn't delete it, it just disappeared after i installed k4pc2.9.1

[random-reader-445072]

I'm not an expert, but for kfxarchiver, the command is:
KFXArchiver291.exe library_location output_folder keyfile.k4i

You had an extra "keyfile" word in there.

the other method, kfxkeyextractor had the keyfile word in it.

so for kfxarchiver: KFXArchiver291.exe "C:\Users\luigi\Documents\My Kindle Content" "C:\Users\luigi\Documents\K4PC2.9.1" kindle_account.k4i

It looks like you don't have book folders in My Kindle Content for whatever reason, just NoteDocuments. Did you download them all?

I followed the instructions you posted and it worked! Thanks, @random-reader-445072!
