OK, it works now, thanks to both of you for the trick!
(it's u'2.0.50727.1434' here)
I applied that patch that was mentioned in Feihong's blog post from the mailing list and built that thing and it works - all three demos running now, and Feihongs test, too.
Just to reiiterate the posting that made the difference:

Dirk,
Disabling that button.Click line makes helloform.py work for me, too. It looks like the Great Firewall is blocking googlepages.com, so unfortunately I can't try that fix -- but that sounds like the right direction.
Here's how to get the version of .NET being used:
>>> from System import Environment
>>> Environment.Version.ToString()
u'2.0.50727.1433'
>>>
Craig.

hmmm ... I have SP1 for sure, but also .NET 3.5 - maybe that is the problem?

Usually you can find a clue by looking in Control Panel > Add/Remove Programs. If you got SP1 or something like that, it'll be listed.

nah, doesnt work here:
D:\projects\pyov>helloform.py
Unbehandelte Ausnahme: System.IO.FileLoadException: Die Datei oder Assembly Python.Runtime, Version=2.0.0.2, Culture=neu
tral, PublicKeyToken=64e14e845abf2e60 oder eine Abhängigkeit davon wurde nicht gefunden. Die gefundene Manifestdefinitio
n der Assembly stimmt nicht mit dem Assemblyverweis überein. (Ausnahme von HRESULT: 0x80131040)
Dateiname: Python.Runtime, Version=2.0.0.2, Culture=neutral, PublicKeyToken=64e14e845abf2e60
bei Python.Runtime.PythonConsole.Main(String[] args)
I probably have to compile it.
Is there a way to find out which .NET version is installed?

This problem sounds familiar. Perhaps you guys are using .NET 2.0 with SP1 applied? Then this blog post of mine might help:
http://feihonghsu.blogspot.com/2008/02/pythonnet-20-for-net-sp1_15.html
If you want, you can try the binary that I made instead of applying the patch yourself.

right you are again. splitter works here, too.
Can you confirm that helloform runs when you disable line 33?
# Register the event handler
# self.button.Click += self.button_Click

Ah, yes. On my system (Vista, Python 2.4 or 2.5, pythonnet-2.0-alpha2) only splitter.py works out of the three demos. I haven't tried to figure out why...

but not really good either, trying to run helloform.py gives me:

Try the UCS2 directory.

Hi,
I get the following error message when trying to run the python.exe from python2.5-UCS4 (I have a fully installed Python 2.5), any ideas? Vista professional here.
