I'm running Windows 7 Ultimate 64 bit on my pc. I have small command line program (exe) which I used in Windows 7 32 bit, earlier. But when I run it on 64 bit OS, it gives an error message

The version of this file is not compatible with the version of Windows you're running. Check your computer system information to see whether you need x86 (32-bit) or x64 (64 bit) version of the program, and then contact software publisher.

I'm planning to install Windows 7 32 bit as a virtual machine & run this exe on it, is there any other way To run it on Windows 7 64 bit OS?

Its probably a 16 bit app - i'd give dosbox a shot, since it would be lighter than running a whole modern windows environment, and 16 bit applications are often dos.

Windows 64 should run 32 bit apps fine, they dropped 16 bit support with 64 bit builds.

Thanks a lot, It worked with DosBox... :) – Nalaka526 Jan 14 '12 at 2:24
Its almost certainly a 16 bit application then – Journeyman Geek Jan 14 '12 at 2:26
