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

In "pydot.py" (located in ...\Anaconda3\Lib\site-packages), replace:

def get_executable_extension():
    # type: () -> str
    if is_windows():
        return '.bat' if is_anacoda() else '.exe'
    else:
        return ''

with:

def get_executable_extension():
    # type: () -> str
    if is_windows():
        return '.exe'
    else:
        return ''

There does not seem to be any eason to add ".bat" when the system is "Windows/Anaconda" vs "Windows" and there may be no ".bat" associated with the ".exe". This seems better than adding a ".bat" for every executable pydot calls...
