I am trying to convert a MOV file, just like you.

It says:

Bink Converter
QuickTime was not able to decompress the audio track (error 1)!

This means either the full version of QuickTime isn't installed,
or your input file uses an obscure or broken audio codec.

In either case, this means you can't export the audio in your movies.

Please try redownloading and reinstalling QuickTime and choose
the Full installation (sometimes uninstalling first helps).

So... I try to reinstall QuickTime and it doesn't work. No clue what to do.
