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
I had this issue and noticed that it was printing my PATH with two sets of double-quotes. I worked around the problem by adding the following to Line 1959 of:
C:\Anaconda\Lib\site-packages\pydot.py
self.progs[prog] = os.path.normpath(self.progs[prog][1:-1])
Obviously not the best fix but it got me through the day.
