Please do read the help page. You didn't tell us if you added
Ghostscript to your path: if you had done so this would not be needed
(as the help page says).

if what you say below is correct, but
would be more standard for recent versions of Ghostscript.

OK, but next time please consult the posting guide and give us the
'at a minimum' information asked for there (we need to know if this is
32- or 64-bit Windows on a 32- or 64-bit OS -- and although rare,
64-bit Windows XP does exist).

BTW, asking how to set environment variables is covered in the rw-FAQ
and is not an R-devel topic.
