Windows 10 Pro
Version 21H1
64-bit O/S, x64-based processor

15:13:16: Audacity 3.1.2
Installed today 27/11/21 (English Date) with FFmpeg v2.2.2 for Windows
avformat-55.dll installed where it should be but Audacityis looking for -58 or -57 
so I cannot save my existing ring-tone (.mid) to iPhone format.
