It only installs numpy into your existing python installation - it
will not overwrite anything else in your python installation (e.g.
everything else should work as before).

You can see numpy as a "plugin" for python, and the binary installer
will just install the numpy "plugin". You will need to have python
installed first.

Note also that if you need more than numpy and scipy, there are also
other options which can make your life easier, like enthought or


In that case, they install many packages related to scientific tasks,
and are self contained. For newcomers on windows, this is the
recommended approach if you don't mind the size.
