As it says it is not found, so you need to check your paths: do 
Sys.getenv("PATH") inside R.

Note that the help page mentions two environment variables you can 
set to the path to the gswin32c.exe, which is designed to make this 
easier for you to set.

Please note that it is getting increasingly important to supply 'at a 
minimum' information asked for in the posting guide.  This is the 
second time that you have not done so, and would-be helpers are put 
off by the lack of basic information.  For example, here we don't know 
the version or build of R (your OS may be 64-bit, is your R)?
