64-bit hardware can run 32-bit OS, but 32-bit OS can't do 64-bit software.
But 64-bit OS can do 32-bit software.
It is the same thing that happened when processors went from 8-bit to
16-bit and 16-bit to 32-bit.
Unlike other versions of Windows, 64-bit Windows no longer supports DOS
programs. The familiar Edit is not there in 64-bit Windows for example.
However, the command line is still there, so those who don't know the
difference between DOS and the command line, will be confused.
I deal with this at work all the time, since we still have some legacy DOS
apps and clients go out and buy a new computer and then wonder why they
programs don't run.
What I have round is the best was to clarify whether you have 32-bit or
64-bit OS if the message you get is not clear is to look at the C:\ drive.
If you only see a "Program Files" directory, then your OS is 32-bit
However, if you see both a "Program Files" and a "Program Files (x86)" then
you have 64-bit Windows.
"Program Files (x86)" is where Microsoft puts 32-bit programs since 64-bit
OSes can run 32-bit programs.
PS - I got a new Laptop at work that is 64-bit Windows. I have the "joy" of
supporting those legacy apps, so I use DOSBox to run them so I can see the
menus to walk clients through procedures, since I don't have those menus
memorized. I also run WinXP in a virtual machine for the older version of
our Windows software that does not run on newer then WinXP and definitely
not on 64-bit. Between the two groups of clients, that's about 40 clients.
Someday they will move into the 90's. :)
