[BioC] problems loading the Rgraphviz package

The Rgraphviz currently available for Windows with biocLite is built
with graphviz 2.16, so you'll need to install
Likely the problem you have below is because the path to graphviz
needs to be added to your system PATH variable, e.g., settings -> control
panels -> system -> advanced -> Environment Variables and then adding
or editing a variable PATH to contain the path to graphviz' bin
directory. My path reads in part
The version of graphviz installed on your computer has to match the
version used to build Rgraphviz, so 2.18 will not work.
