Hi Deepak,

Likely your PATH variable is set incorrectly. From within R you should
be able to do something like


> ## which element is supposed to point to Graphviz?
> strsplit(Sys.getenv("PATH"), ";")
$PATH
...
[12] "c:\\Program Files\\Microsoft SQL Server\\100\\DTS\\Binn\\"
[13] "C:\\Program Files\\Graphviz2.20\\bin"
[14] "C:\\Program Files\\SAS\\SharedFiles\\Formats"
...
> ## does it point to the right place?
> list.files(strsplit(Sys.getenv("PATH"), ";")[[1]][13])
...
[29] "lefty.exe"                      "libcairo-2.dll"
[31] "libcdt-4.dll"                   "libcgraph-4.dll"
[33] "libexpat.dll"                   "libfontconfig-1.dll"
...
