Hi!
   I am having this problem too. Since I upgraded to Windows 8.1. today my 
Python.net installation has stopped working:

import clr
SystemError: dynamic module not initialized properly

I have not built my own Python.net (and would rather not if possible as I 
am not sure what is involved - I suspect I would have to set up lots of 
things I currently don't have, but just used the latest version at 
http://sourceforge.net/projects/pythonnet/files/.

Has anyone rebuilt Python.net using the patch suggested in David's message 
above, and either has, or is willing to, make it publicly available 
somewhere in a gzipped form that could just be downloaded and copied into 
my Python setup. I would be really really grateful!

Many thanks.

Hoping ...

Rudi
