is it possible to install 2 Python versions on windows XP ?

[Stef Mientki]

hello,

I'm currently using Python 2.4,
and I don't dare to switch to 2.5,
because I depend heavily on Scipy, which is based on 2.4

To test some other Python programs I need Python version 2.5.
I've tried to install 2.5 in the past,
but got a lot of trouble trying to uninstall it to go back to 2.4.

Is there a safe way to install Python 2.5,
without affecting the Python 2.4 version and  the windows registry,
on windows XP ?

thanks,
Stef Mientki
