FastFlix v4.0.0 Windows Installer - Unable to launch

Hello,

Fresh install, no previous versions. It launches, offers to download ffmpeg, I agree, it finishes downloading then closes.

Hopefully this fixes this issue https://github.com/cdgriffith/FastFlix/releases/tag/4.0.1b0 for anyone else experiencing it.

Will wait a few hours for any other Day 0 bugs from the 4.0 release and release it officially tonight or tomorrow morning.

Very odd, I will try to re-create that behavior and see what’s going on.

For time being, can manually create the config file with proper paths to fix it:
