[ Below is the answer I just sent to your original request on the scipy list. 
  Duped here for reference, and in case a win9x user has further insights ]

Sorry for missing this one on the first pass.  The problem is most likely due
to the post-install script not being compatible with Win98.  I don't have
access to win32 machines, and win9x is getting rare these days, so things are
hardly tested there.

You can just install ipython manually yourself: it won't give you start menu
icons and whatnot, but it will work.  From the README_windows.txt file:


Double-click the supplied .exe installer file.  If all goes well, that's all
you need to do. You should now have an IPython entry in your Start Menu.

In case the automatic installer does not work for some reason, you can
download the ipython-XXX.tar.gz file, which contains the full IPython source
distribution (the popular WinZip can read .tar.gz files). After uncompressing
the archive, you can install it at a command terminal just like any other
Python module, by using python setup.py install'. After this completes, you
can run the supplied win32_manual_post_install.py script which will add
the relevant shortcuts to your startup menu.


Chances are the win32_manual_post_install.py won't run even manually for you,
but all it does is make some convenience Start menu shortcuts (ipython and
manuals, mostly).  You can either live without them, or make them by hand.
They are not essential for ipython's functionality.

I hope this helps, let me know if you have any further questions.
