Ok.  Let's back up and check a few things. Does the command below run 
Ghostscript ?

        system gswin64c.exe

If not, what does the following return.

        getenv path

If you see 'C:\Program Files (x86)\gs\gs9.05\' in the path, what does the 
command below return ?

        dir 'C:\Program Files (x86)\gs\gs9.05\'
