I had the same problem and the following fix in the file
runtime/assemblymanager.cs made things work for me. I believe the problem is
that on Win 8.1 there seem to be generic types that aren't in a namespace.
My patch just skips those and thus prevents a crash. I am not sure whether
that is the right way to handle it, but it does fix the crash.
Best,
David

Subject: [Python.NET] Python .NET on Windows 8.1
I have been using python.net for about 5 years for my project at work.
Usually everything worked or at least there was a way to fix it. Right now,
there is a situation, that I cannot understand.
Since my PC got upgraded from W7 to W8.1 imports stopped working. It seems
that something happens on clr module initialization stage, because when I
try clr.AddReference("...") python answers: "AttributeError: 'module'
object has no attribute 'AddReference'"
When debugging with freshly built clr.pyd/Python.Runtime.dll I see that
Runtime.Initialize() finishes without exception and clr module methods are
added via InitializeModuleMembers(). Yet still, when I run my program clr
doesn't work properly and seems like import hooks are not there
(breakpoints at AddReference and other methods are not fired).
Do you have any pointers for me in this situation?
Thank you,
Mihhail Maslakov

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
