i'm using IronPython and i want to create some windows form, 
i want to create a windows form with some button, and i want to do this in visual studio with iron python,
i'm using visual studio 2012 integrated edition,
each time i create an "ironpython windows form" project, when i want to run it, it says:

The project is currently set to use the .NET debugger for IronPython
  debugging but the project is configured to start with a CPython
  interpreter. To fix this change the debugger type in project
  properties->Debug->Launch mode

when i change debugger to Standard Python Launcher, it says:

ImportError: No module named clr

what should i do?
I got the same error and resolved it with these steps:
I changed the project properties
General>Interpreter to IronPython 2.7
Debug>Launch mode to IronPython(.NET) launcher
At first I didn't see IronPython as an interpreter option to select from. I added the path to IronPython installation to my Path System variable, restarted Visual Studio and it worked.
Cpython interpretter / IronPython interpretter No module named clr
