[Python.NET] Python.NET and VS2010/.NET 4.0

[Bart Jonkers]

Hi Oleskii,

Thanks for the quick response.

I searched on my system for the python26.dll and I found it in
C:\Windows\SysWOW64.
I copied it to c:\windows\system32\ and now I'm getting the following error:

Unhandled Exception: System.BadImageFormatException: An attempt was made to load
 a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
   at Python.Runtime.Runtime.Py_Initialize()
   at Python.Runtime.Runtime.Initialize()
   at Python.Runtime.PythonEngine.Initialize()
   at Python.Runtime.PythonConsole.Main(String[] args)

Anny idea?

I have installed python 2.6.6 (32-bit) on a 64-bit version of Windows 7.

The problem that we have with the .NET version of python.exe is that
it takes some time before it starts.
As we use python in our build environment, it significantly slows down
our build process.

Regards,
Bart
