ELI5 kfxarchiver282 running, but no output

[busy-broccoli]

kfxarchiver282 runs fine, seems to find keys for all books with hidden keys, but doesn't output anything. I created the output folder I direct PowerShell to, but nothing is written to it. I'm sure it's a simple user error, I just don't have the knowledge to figure it out myself. I looked at discussion #55 to get this far, but now I'm stuck. Thanks for any help.

deDRM v10.0.20
K4PC 2.8.0

edit: There was an issue with my cmd prompt so now I have one .k4i file in the output folder, but I still don't know how to transfer my books into Calibre without DRM. Techy-Notes tutorial no longer works for me for whatever reason.
edit 2: I was running the extractor (hence the 282 in my title), not the archiver. I am clearly not a tech-savvy human, forgive me.
