Which versions of Emacs/ESS are you using?
For Windows, the mostly widely used is the "Emacs for Windows
modified" jumbo package
from Vincent Goulet (quickly found from the 'Download" tab on

I won't be the person to help you in detail here,  but for others to
help you, it's of importance to know with which configuration (Emacs
<-> ESS ) you are working.

ESS itself is setup in principle to recognize (and support via  M-x R,
M-x R-<ver>)
*several* versions of R available on the given computer.
But indeed, the detection of these versions is platform dependent
and may work differently are not optimally anymore with the new
64-bit/ 32-bit  multi-architecture installations.
