To avoid all the hassle I suggest getting EPD: http://enthought.com/products/epd.php
You'd get way more than just NumPy, which may or may not be what you need. 
I have installed various NumPy's on linux only and from source only which did 
require compilation (gcc), so I am not a good help for your setup. 
On the hand, I've done multiple EPD installations on various platforms and never had problems.

Hi,

I am trying to install NumPy (using  numpy-1.6.1-win32-superpack-python2.7) on a Windows 7 machine that has 32-bit Python 2.7 installed on it using the latest installer (python-2.7.2.msi).  Python is installed into the default location, C:\Python27, and as far as I can tell the registry knows about it -- or at least the windows uninstaller in the control panel does...

The installation fails because the NumPy installer cannot find the Python installation.  I am then prompted with a screen that should allow me to type in the location of my python installation, but the text-boxes where I should type this do not allow input so I'm kind of stuck.

I did look into trying to build from source, but I don't have a C compiler on this system so setup.py died a horrible death.  I'd prefer to avoid having to install Visual C++ Express on this system.

Does anyone have any suggestions that might be helpful?

Thanks!
