"The version of this file is not compatible with the versions of Windows you're running. Check your computer's system for information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program." This is what keeps happening when I try to install a CD for the program 'Body Works: a 3D Journey Through the Human Anatomy'. I have checked my computer's properties and it is running a 64-bit operating system. I don't know if this helps, but on the CD package it says "Window's 95" "Windows 3.1"rmason1210[at]yahoo.com
No; Windows 95 was a 32-bit OS. But many programs of that era were designed to run on Windows 3 also and so were, as you say, 16-bit programs. A further complication is that some older 32-bit programs used a 16-bit installer. Some of these can be made to run on 64-bit systems with a little trickery, but not all.
I suspect the only way you could run this program on your PC would be to run Windows 95 in a Virtual Machine.
