Yes, it is possible, and as a matter of fact, it is mandatory now and
then.  The basic idea is that 32-bit programs go under:

    C:\Program Files (x86)\

and 64-bit programs under:

    C:\Program Files\

Now the fun part begins: Programs are not allowed to write into
sub-directories and therefore they are forwarded to:

    C:\Users\<USERNAME>\AppData\Local\VirtualStore\Program Files (x86)

For me, it never worked reliably for the Linux ported programs I use.
So I gave up on it and install programs not developed for Win outside
those directories.  Mixing 32- and 64-bit programs is not a problem.

Within AUCTeX?  Which one do you mean?  I see none, or am I missing
something?

(defvar TeX-view-program-list-builtin
  (cond
   ((eq system-type 'windows-nt)
    '(("Yap" ("yap -1" (mode-io-correlate " -s %n%b") " %o") "yap")
      ("dvips and start" "dvips %d -o && start \"\" %f" "dvips")
      ("start" "start \"\" %o")))
    ((eq system-type 'darwin)
      ...

Best, Arash
