No, seriously. It doesn’t detect it automatically and even when I enter the way manually. Version 2.2.1
UPD.: Updated to v2.3.0. Still have the problem
The newer download is for the newer 64-bit version of Audacity.
You’ll need to install the 32-bit version of FFmpeg from [u]this page[/u]. Download and run ffmpeg-win-2.2.2.exe and it should install and you should be ready to go.
