I am getting the same exception on Windows. It hangs for a long time as if it is downloading but finally gives this exception. I am thinking it is trying to unzip the downloaded file.

I have since gotten another exception: "Access to the path 'C:\WINDOWS\system32\ffmpeg.exe' is denied." I don't know why it would be trying to put it there since I pointed it to the Assembly.GetEntryAssembly().Location.

I've found one issue with downloading code.
Exceptions was silently catched and process continues: that might have been a problem with "Central Directory corrupt"
I've pushed code to master and deploy it this week but can't reproduce that issue so I'm not 100% sure that it will help

Thanks, Tomasz. I have been able to move past this problem by just copying ffmpeg.exe and ffprobe.exe from the assembly folder of Xabe.FFmpeg to the assembly folder of my app. Currently I'm trying to figure out how to make Xabe.FFmpeg convert from .wav audio to .mp3. I already do this with Laerdal.FFmpeg.Audio for Android and iOS so I know that FFmpeg.exe can do this conversion.
