When you installed Ghostscript, what was the "Destination directory"?

DId you set "gs_path" to the "Destination directory" in ~\.octaverc?

Using the default destination directory for 32 bit Win7 the adds to include in 
~/.octaverc are ...

    cmd_path = getenv ("path");
    gs_path = 'C:\Program Files (x86)\gs\gs9.05';
    if (isempty (strfind (cmd_path, gs_path)))
      setenv ('path', strcat (cmd_path, pathsep (), gs_path));
