Your timing is perfect.  The newest release of ESS 12.09, which probably
will be released next week,
will provide the solution.  ESS through the current release on Windows
finds all versions of R stored in
the default installation location "C:/Program Files/R/".  Since you have a
different
location, the versions are not found.

Once 12.09 is out, you will add a new line to your .emacs file prior
to starting ESS. The exact phrasing is still in flux.
