  • Hello.

    64-bit Windows (any version from XP and up) doesn't support 16-bit applications.  All is not lost however!  You still have several options available:

    Perform an Anytime Upgrade to Windows 7 Pro or Ultimate and use XP mode.  (The home versions don't support XP mode.)

    Install virtualizing software such as VirtualBox (http://www.virtualbox.org/) or Virtual PC (http://www.microsoft.com/windows/virtual-pc/support/virtual-pc-2007.aspx) and run a retail version of XP in a virtual machine (requires a separate XP license).

    Contact your system vendor and see if they'll send you the 32-bit version of Windows 7. (assuming you don't mind the 32-bit version; this would require a complete reinstall.)

    Download and install DOSBox (http://www.dosbox.com/) and try running it in that.  (This is a DOS 16/32-bit emulator, not a virtual machine.)
