need advice on installing NumPy onto a Windows 7 with Python2.7 (32bit)
Hi,
I am trying to install NumPy (using numpy1.6.1win32superpackpython2.7) on a Windows 7 machine that has 32bit Python 2.7 installed on it using the latest installer (python2.7.2.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 textboxes 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! William
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. Val

It seems weird that it wouldn't work, as this is a pretty standard setup. Here's a few ideas of things to check:  Doublecheck it's really 32 bit Python (checking sys.maxint)  Is there another Python installation that may cause some conflicts?  Did you download the numpy superpack from the official website?  Reboot
Unlikely to be helpful, but I can't think of something else right now :/

Yup, it's 32bit python: Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32 Type "copyright", "credits" or "license()" for more information.
I've only got one python instance installed here :D
Here's where I got the numpy installer, http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/, as far as I can tell this should be the right place.
Python has been installed on this system for a while and it's been rebooted numerous times, I can't imagine that it wouldn't be there. Matplotlib's installer had no trouble finding Python.
Thanks! William

Sorry then, I'm afraid I'm out of (simple ideas). Out of curiosity, I tried to install Python 2.7.2 and numpy 1.6.1 on a Windows 7 computer and it worked just fine, so it must be something with your specific setup...
