Were they all on the same machine and user? If so, I don't know why it wouldn't find it automatically. But you can set Kobo's directory in Obok. Preferences > Plugins > select Obok DeDRM (under User interface action) > Kobo directory

In Windows, it should be here: C:\Users\USERNAME\AppData\Local\Kobo\Kobo Desktop Edition\kepub

yes, they all on the same machine and user. i set Kobo's directory in Obok ,but it still said can't find kobo library. so weird... so i back to calibre4.23.0 and obok6.5.4 .......... anyway, thank u!!

Very odd. I'm able to use Obok 10.0.3 with calibre 6.7.1 on Windows 10 without issue.

Hey, just a hunch, since I have this same message appear. What do you set your Kobo directory to?

I used to have it set to /Users/{my_user}/Library/Application Support/Kobo/Kobo Desktop Edition/kepub on my Mac. This is the directory where the actual books are stored.

It's probably documented, but I only figured it out after reading the code: https://github.com/apprenticeharper/DeDRM_tools/blob/776f146ca00d11b24575f4fd6e8202df30a2b7ea/Other_Tools/Kobo/obok.py#L365-L367

this part here searches your set Kobo directory for the presense of Kobo.sqlite database, in my case it's located one level above, at /Users/{my_user}/Library/Application Support/Kobo/Kobo Desktop Edition. After setting that as a directory my issue was resolved.

Furthermore looking at the debug you've provided, I think you need to make it slightly more precise. Can I suggest you run Calibre in debug mode? In my case (M1 Mac) it's possible by running a Terminal commad: /Applications/calibre.app/Contents/MacOS/calibre-debug -g. This then opens Calibre and also outputs whatever is configured to be output in the code to the Terminal. In my case it used to output: got kobodir whith no dir listed, this is how I got a hunch on where exactly in the code I need to look to get what went wrong.

Hope it helps.
