Not exactly - Windows 7 Pro 32-bit will run most 16-bit software just
fine. Windows 7 64-bit, however, will not and requires either XP Mode
(for Pro/Enterprise) or some other virtual machine, such as VMWare,
Virtual PC, etc. running a 32-bit version of Windows (or pure DOS, for
the hard-core).

If you are saying that Windows 7 64-bit won't run 16-bit software
natively, that is correct. However, the version of XP Mode that comes
with Pro/Enterprise runs a 32-bit copy of XP so it is capable of
running 16-bit software. Same with MS Virtual PC, assuming a 32-bit
version of Windows is installed there of course.
