On XP, even though the DLL is in the PATH, it is not loaded when emacs runs, according to Process Monitor. The XP system contains only the files in emacs-24.4*.zip. I have added files (usually extra modes) to my main emacs installation over the years, although I would not be able to say what I have added. If there is another startup file that is read besides .emacs, that may be answer.
