One of the ongoing problems with QR code is how frequently ugly they are. So when I found a downloadable software program that improved on the look, I had to check it out. Unfortunately, this is 100% just a demo and doesn't generate anything other than default codes.
Hopefully this post will save someone else the time trying it out.
