ImportError: DLL load failed; Python 2.7; Windows 7

[csp]

Hello,
I have the enthought python distribution installed on a PC running
Windows 7. I have encountered the following error message when trying
to import dadi (see paste from console window below). The other site
packages work fine. I also included the sys.path output in case that
is helpful.
Thanks in advance for any advice! I am new to dadi.

Hello csp,

Thank you for including the error messages and sys.path. I suspect that
the problem is that we provide an installer for 32-bit python, and you're
running on 64-bit python.

The easiest solution is likely for you to build dadi yourself. Since your
Python shell indicates you installed the Enthought distribution, you
should have everything you need. To build and install your own version of
dadi:
1) Download and unzip the dadi source
2) In the top-level source-code directory, run 'python setup.py install'.
This will install dadi, including the C extensions that make dadi fast.

That should be it! Let me know how it goes.

Cheers,
Ryan
