Well, this has been discussed before. The consensus seemed to be look it up in
the registry. See the following article for a batch file that you can run from
elisp to authoritatively find R:

Here is a workaround for those who are not faint-of-heart in working with .el files.
If it works for you and others, we can put it in a future release of ESS.
In your example, select the second line and comment out the first.
I tested it on Windows 7 with ESS 12.04-4 using the first line and the third line.
On proper installation, the first three lines will become potential values for a new
customized variable, and the first line will be the default value.

I recently installed R in a Windows directory other than the default
to help Rcpp play nice on Windows. Unfortunately, ESS cannot find any
versions of R on my system now. My "exec-path" contains a path to the
"bin" folder of the new installation of R, and I even tried adding
two additional paths to the "exec-path" (the "bin/i386" and "bin/x64"), but
this did not seem to help.
P.S. I'm using Vincent Goulet's fabulous windows Emacs bundle, if that's
useful information for anybody.
