However, it gives me the "Error Import" dialog with the link to file:///.../audacity/help/manual/man/importing_audio.html

FFMPEG library is detected as F(55.33.100), C(55.52.102), U(52.66.100).

On the side, it would be nice if the text throughout the application / dialogs is somehow selectable/copyable

Can you play the file? (With Windows Media Player, etc.?)

If you can play the file you can record it while it's playing.

Or if VLC can play it, there's a way to extract the audio with VLC (and optionally save it in a different format) but I've never tried it.

If you can't play it, maybe it is corrupted....

I have extracted it successfully with e.g. https://audio-extractor.net/ (I couldn't think of a faster solution)

On Linux it is, but apparently Windows does not support copying from a wx message (wxMessageDialog) window.
9/10 questions are answered in the FREQUENTLY ASKED QUESTIONS (FAQ)

Good to know that it was build with that in mind :-D
