I have just looked at installing ESS 5.2.11 under GNU Emacs 21.3 on

default locations. ESS have problems locating R when I try to start  
an inferior R process.

The help page for ess-rterm-versions says

ess-rterm-versions is a variable defined in `ess-cust.el'.
Its value is nil

*Construct ess-rterm-versions.  If you have versions of R in
locations other than in ../../rw*/bin/Rterm.exe, relative to the
directory in the `exec-path' variable containing your default location
of Rterm, you will need to redefine this variable with a
`custom-set-variables' statement in your site-start.el or .emacs

You can customize this variable.

If the help page is up to date with the code, it seems that ESS is  
looking in ../../rw**, where R used to reside. Now a days, Rterm.exe  
has the location ../../R/R-2.2.1/bin/Rterm.exe (relative to Emacs  
eing installed in c:\program files). My lisp abilities are missing,  
but I assume this would be a very easy bug fix. I suggest keeping the  
search in the old location. For now, I have just used inferior-R-
