Instead of uncommenting those lines, passing t to executable-find's
second argument should work. Can you check if this solves your issue?

#+begin_src elisp
  (unless (executable-find inferior-ess-r-program t)
    (display-warning 'ess (format "%s could not be found on the system. Try running `R-newest' instead, which searches your system for R." inferior-ess-r-program) :error)
    (user-error "%s program not found" inferior-ess-r-program))
#+end_src
