After installing the latest graphviz (2.26.3) on my Windows 7 Ultimate 64bit, I receive the following error:

Here's what worked for me. Precondition: Install mingw32 (included in pythonxy distrib if you're using it), Graphviz
1) Download pygraphviz sources
2) Edit setup.py to change paths to smth like
library_path=r"c:\Program Files (x86)\Graphviz 2.28\bin"
include_path=r"c:\Program Files (x86)\Graphviz 2.28\include\graphviz"
Note that it's \bin, not \lib. Linking with libs didn't work for me.
3) run python setup.py build -c mingw32
Result of step 3:
c:\Python27\Lib\site-packages\pygraphviz-1.1>python setup.py build -c mingw32
library_path=c:\Program Files (x86)\Graphviz 2.28\bin

4) copy the result from the just built lib.win32-2.7 (single sub-folder called pygraphviz
) into your Python's site-packages folder
Enjoy!
