Why is pydot unable to find GraphViz's executables in Windows 8?

Question

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

Answer 1

This happened because I had installed graphviz after I had installed pydot. Hence, pydot wasn't able to find it. Reinstalling it in the correct order solved the problem.
