Export to ALAC via External Program Errors

Hey All,
Hoping someone here can help or has experienced this before
I wanted to start exporting direct to ALAC and have been trying without success.
I followed all the directions, placed the linked FFMPEG binaries in the audacity folder under lib, added path and binary to external program path with the additional command line string but I either get an error saying the binary cannot executive or I get an error 13. I’ve included a few screen shots if that helps

I could just export to wav and then convert when they come into music which is what I have been doing. but I would much rather prefer this method.
macOS Monterey 12.0.1
