Thank you, Rich, for the clarifications.
Indeed, also with Vincent's installation, for me,

	 M-x R-2.5.1pat
or	 M-x R-2.4.0	(which I had installed there a while ago)

did work out of the box.
However --- after commenting out Vincent's site-start.el 's
(setq-default inferior-S-program-name "c:/program files/.......")

	      M-x R
still did not work, but differently :

It tried to call "rterm" (or "Rterm" ?, don't remember exactly),
and did not find it, since it was not in my Windows PATH
or exec-path respectively.

It would be nice to improve ESS here,
and make  M-x R  behave as you said it would behave,
namely, from all the
find the newest one and use that.
