Compiled project crashes when frozen with cx_freeze #66
Description
Machine specs:
Windows 7 64bit
Python 2.7 32bit
.Net Framework 4.5.2
I download the repo for pythonnet and built the project using ReleaseWin on platform x86 using visual studio 2012.
pythonnet works fine but once i freeze the app using cx_freeze the app crashes.
It worked well with the source forge version but fails on windows 8 and 8.1.
After googling around i found that building the repo using x86 solves the problem.
Please anyone knows a fix ?

I'm getting the exact same error as here: http://stackoverflow.com/questions/26110026/pyinstaller-and-pythonnet-clr
I've tried cx_freeze, py2exe and pyinstaller. I'm using Python 2.7 64bit, Windows 7 64bit. and I have a bunch of .Net frameworks installed, including 4 and 4.5.
Is it at all possible to create an exe that using python.net?

@jfbramboll @kelvinomolumo PyInstaller should provide a hook to include pythonnet:
pyinstaller/pyinstaller#637
it is reportedly working for people here:

I am not sure about cx_freeze

pyinstaller has been updated to include proper clr (pythonnet) hook:
pyinstaller/pyinstaller#1801

In order to stop crashing with cx_freeze you need to manually add Python.Runtime.dll file from pythonnet package to your binary directory.
den-run-ai commented on Mar 6, 2017
@konstantin-popov does cx_freeze allow configuring hooks for various packages so that this works by default?
konstantin-popov commented on Mar 6, 2017
Not sure, but I think it does, looking at this: https://github.com/anthony-tuininga/cx_Freeze/blob/master/cx_Freeze/hooks.py
den-run-ai commented on Mar 6, 2017
@konstantin-popov feel free to submit a pull request to cx_freeze to implement this hook based on pyinstaller implementation. We cannot do anything about this in pythonnet without breaking a lot of code.

Sure. My reply was not a call to action, only a recipe how to deal with this specific problem - actually not with patching cx_freeze, but with adding a file to build using configuration options (option 'include_files').
The ticket you mentioned is actually about a different problem - failing to import custom .NET libraries in frozen app.
den-run-ai commented on Mar 6, 2017
@konstantin-popov you need to update sys.path in order to custom load your .NET assemblies. See fairly complicated example for pyinstaller here:
#325
konstantin-popov commented on Mar 7, 2017
I do update sys.path and clr.AddReference('customlib') throws no exceptions - the problem appears later in code when importing the assembly.
I guess pythonnet hooks into python import system to load .NET assemblies, but after freezing the app with cx_freeze in doesn't work for some reason.

Is there a traceback available?
den-run-ai commented on Mar 7, 2017
@konstantin-popov minimum reproducible example would be handy. Also make sure that your library does not reference other custom assemblies, maybe even during runtime.
konstantin-popov commented on Mar 10, 2017
That was exactly the thing. The library was external so I didn't guess it referenced somethine else. Thanks @denfromufa!
P.S. PR with a hook for pythonnet in cx_freeze
anthony-tuininga commented on Mar 11, 2017
Pull request merged.
den-run-ai commented on Mar 11, 2017
@jfbramboll @kelvinomolumo can you please verify that the pythonnet hook is now working in cx_freeze? @anthony-tuininga @konstantin-popov thanks for implementing this!
Anyway if any issues come up we can reopen this issue.
