Unpack the distribution using an unzipping utility such as 7-Zip (http://www.7-zip.org/) that understands gzipped-and-tarred files. Once you've done that, open a shell by left-clicking on "Start", selecting "Run", and typing cmd into the box. Navigate to the directory into which you unpacked the PyPedal distributio(this is an example, your file location may vary):
C:\> cd C:\PyPedal
Build it using the distutils defaults:
C:\PyPedal> python setup.py install
This installs PyPedal in C:\python24\site-packages.
