Dear all,
I am facing the same problem. I followed the all instructions given in help
file and some steps of previous discussion (from google search) but I could not
install package Rgraphiviz in windows. I tried even the instructions given to
install Bioconductor package then only able to install in Linux systems but not
in Windows. In my opinion, Graphiviz package which creating problems in
installation of Rgraphiviz packageis, is doing something wrong or needs some
special requirements .
If some body have idea regarding this problem, I am also enthusiastic to see
the solution.
Pls, if you find solution, let me know.
Thanks
Truly,
Ram Kumar Basnet,

Rgraphviz is a Bioconductor package, so please ask on the apporpriate
mailing list (see the posting guide).

It should be 'PATH', not 'path': environment variables are
case-sensitive
(in general, not sure what happens with PATH if set there).

That does not mean Rgraphviz.dll: it means a dependent DLL. You did
actually install graphviz, I presume?
