I have the same installation problems on two 32 bit computers running
Windows 7 or Windows XP. and R 2.12.0
The shared object RGraphviz.dll is where it is supposed to be.
Any suggestions greatly appreciated.
Using R version 2.12.0, biocinstall version 2.7.4.

Check that (1) graphviz is installed on your system; (2) the installed
version of graphviz matches '2.20.3'; this is the version used to build
this Rgraphviz package; (3)
graphviz is accessible to R, e.g., the path to the graphviz 'bin'
directory is in the system 'PATH' variable. See additional instructions
in the 'README' file of the
Rgraphviz 'source' distribution, available at
