I have GraphViz 2.32 installed in Windows 8 and have added C:\\Program Files (x86)\\Graphviz2.32\\bin to the System PATH variable. Still pydot is unable to find its executab
The solution is easy, you just need to download and install the Graphviz, from here.
Then set the path variable to the bin directory, in my case it was C:\Program Files (x86)\Graphviz2.38\bin. Last, do the conda install python-graphviz and it should work fine.
