Yes, it is possible. What version of ActivePython do you currently have
installed (I work for ActiveState, BTW)? 

You cannot have two versions of Python with the same major and minor
version numbers installed at once (*) i.e. you cannot have ActivePython
2.2.0 Alpha and PythonLabs Python 2.2b2. If you have ActivePython 2.2
installed, I would recommend uninstalling it, installing ActivePython
2.1 and then installing PythonLabs Python 2.2b2. You will be able to
using the last stable Python for your Win32 development and the
bleeding-edge release for fooling about.

(*) with a bit of hackery, anything is possible of course, including
(**) only the truly insane (like Guido) try to develop on W9x.
