After looking up previous posts on the R and bioconductor lists, I installed the Rtools29. I have checked that the paths are correctly listed on the environmental variables window.

You should use the binary that's available.  If you follow the 
instructions that are in its README file, it works. (These include 
installing graphviz first:  the R package is just an interface to it.) 
Building it is not easier than getting the prebuilt one to work.
