Most 32 bit programs will run without problems on 64 bit versions of Windows
running on x64 CPUs.
Itanium and other 64 bit CPUs are a different story, but AFAIK Windows 7 runs
on none of them due to Intel abandoning attempts to fully break with the x86
and x32 past.
For software that absolutely will not run on Vista or Win7, even in a
compatibility mode, Microsoft has the free "XP Mode" download, but it only runs
on the higher end versions of Vista and Win7. It also has some limits on
functionality.
An alternative is VMLite XP Mode which is also free. It uses the same Win XP
image download as Microsoft's XP Mode. This has several advantages over
Microsoft's version.
1. It can run on lower-spec hardware than the MS version requires, though
performance may suffer.
2. It has more direct hardware access so you can run apps like games that need
3D acceleration.
3. Does not require a patch to run on CPUs without hardware virtualization
support and most likely will outperform the MS version on such CPUs.
4. Supports 3rd party virtual machine images, ie from VMWare and others.
5. Runs on almost every version of Vista and Win7 *and* Windows XP.
6. Can run newer guest versions of Windows on older host versions. MS XP Mode
only runs XP and only on Vista and Win 7.
7. Can run a 64 bit guest OS on a 32 bit host OS running on a 64 bit CPU. (This
trick requires hardware virtualization and at least a dual core x64 CPU.)
Those last two mean you could run Adobe's latest 64bit software "seamlessly"
with Windows XP Pro 32 bit, as long as you have the newer Windows install disc
to setup a guest OS image.
If you have a lot of software that is very incompatible with Vista or Win7 and
want/need a few programs that need Vista or Win7, that's when it'd be ideal to
use VMLite for running the software needing the later Windows version.

Another trick up VMLite's sleeve is the "sandbox" where the app it's running is
completely walled off from the host and no permanent changes to the guest OS
image are allowed. One use for this is testing a setup or install to see that
it puts everything where it's supposed to go.
