How do I run a 32 bit DOS program on 64 bit? Is it possible?

Computer is Windows 7 professional and is 64 bit. I always ran a Dos program on XP prof 32 bit-cannot run it on new computer. DOS program uses QA and Lotus.

DOS programs are typically 16-bit. What program(s) are you trying to run?

Yep, pretty much the only option is a VM running Windows XP, that way everything is the same. Look up Windows XP Mode for Windows 7. http://windows.microsoft.com/en-us/windows7/install-and-use-windows-xp-mode-in-windows-7

Other option would be DOSBox. http://www.dosbox.com/

Don't let the appearance that it is for gaming fool you. It can run a lot of DOS based applications.

Or you could try vDos (http://sourceforge.net/projects/vdos/).
It does a far better job in emulating DOS for programs like QA and Lotus.
