Subject: [PATCH] - Check for existence of external executable   + With the
 check we can exit early and provide a message to the user     that the
 executable is missing, rather than having the information about     the
 missing executable intermingled with a failed call thereof. Last     but not
 least it avoids the message that indicates that a download is     being
 attempted, which could lead to confusion.
