This is a bioconductor package so please ask on the Bioconductor mailing
list

http://bioconductor.org/docs/mailList.html

See the 'README' file in the 'tar.gz' file at


  http://bioconductor.org/packages/release/Software.html
  http://bioconductor.org/packages/2.5/bioc/html/Rgraphviz.html



http://bioconductor.org/packages/2.5/bioc/src/contrib/Rgraphviz_1.24.0.tar.gz

which says


o. install Graphviz ***2.20.3.1*** Windows ***binary*** distribution from


http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.msi

you must use this version of graphviz. File paths must be correct.
