Should these files be part of the installation package?

No, because Audacity cannot distribute those due to licensing issues. FFmpeg lets you import and export additional audio formats in Audacity.

If you require FFmpeg, please visit How do I download and install the FFmpeg Import/Export Library? .

Added info:

Most of the codec .dll files are located in the K-Lite directories. But none with the ‘-55’.
Only ‘-56’, ie avformat-ics-56.dll

If you wish to use FFmpeg with Audacity, please see: http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown

Thank you both for the FF fix. Although I don’t use the program very often, it has been very handy when I did need some of the options available.
I probably will never use the FF options, but I just don’t like seeing error messages no matter what the cause.

I understand it’s potentially confusing if you did not intend to install FFmpeg. However if you did intend that, the debugging information can be very useful.
