I am trying to run a DOS application (.com) in Windows 7 64bit. It will not run on anything newer than XP. Is there any way? I can set the comand prompt to run in XP compatibility mode? The only options I'm seeing are Vista and Server 2008.
I have tried DOSBox, and I can't seem to get OS/2 to install under virtual box.

Windows 7 64bit does not support a 16 bit sub system, so no 16bit DOS applications will run in Windows 7 64bit. Your title is not quite clear, Maybe you are using the wrong term, here is what XP Mode is, and may be the solution you are looking for.
