Windows 64-bit does not support 16-bit applications.  You will have to do this from a dual-booted OS with a 32-bit OS or using virtualization (XP Mode, etc.) from within Windows 7.

What PowerEdgeTech says is accurate, except:
> I have windows7 home edition
XP Mode is not available for you.  You would have to install Virtual PC or VMWare Workstation and then purchase a copy of XP to do the rough equivalent.

you could use the Any Time Upgrade to Upgrade to Windows 7 Ultimate which would include XP Mode rights.

You likely cannot downgrade as I suspect Windows 7 came with your PC and OEM installs rarely (if ever, in my experience) include both options - you're stuck with what was pre-installed unless you purchase a new license.

XP Mode (Professional, Enterprise, and Ultimate - $90 to upgrade from Home Premium to Professional, but you get a fully-licenesed, pre-configured virtual machine of XP Pro that runs from within Windows 7):

Virtual PC (is available without XP Mode too - on link above, click on this line - you must however have a valid/unused key and media for this or any of the options below):
Download Windows XP ModeDownload Windows XP Mode with Virtual PC
"Don’t need XP Mode and want VPC only? Download Windows Virtual PC without Windows XP Mode."

You can also use VMWare Player or VirtualBox as free software for running a virtual machine.

XP is 32 bit.  There was a 64 bit version, but you'd know if you had it - it wasn't commonly sold/distributed.

64 bit operating systems (all Microsoft 64 bit operating systems) do not support 16 bit programs.  They should run* 32 bit programs fine though.
32 bit operating systems (all Microsoft 32 bit operating systems) do not support 64 bit programs but should run* 16 bit programs.

*There are exception, especially in the area of drivers and hardware interface programs (CD burning software, for example).
