Hmm, I'm guessing it's a 64-bit versus 32- or 16-bit issue. Is Composer old enough to run on Windows 3.1? Theoretically, it is possible to set up DOSBox to run a Windows 3.1 session under Win10. I haven't tried that yet, but I need to for some uses of my own; I will try to post about it when I finally get around to it.
