[BioC] Problem in installing Rgraphviz

[Heba [guest]]

Hello, 
I am having problems in installing Rgraphviz package on Windows 7. I followed the instructions in the read me file @ http://bioconductor.org/packages/2.9/bioc/readmes/Rgraphviz/README

I installed the graphviz 2.20.3.1 to C:\Graphviz2.20 from this link:
http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.msi 

I added C:\Graphviz2.20\bin to my system PATH variable and I can see the change in the DOS command window as following

C:\Users\acapella>echo %PATH%
C:\Python27\Lib\site-packages\PyQt4\bin;C:\Program Files\Common Files\Microsoft

\;C:\Graphviz2.20\bin


Then I installed the package using biocondutor but when try to load the library or call specific function it give me the following outputs

  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

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

Error: package/namespace load failed for ‘Rgraphviz’




Can you please help me identify the problem?

Thanks,
