Remove old version before upgrade?

[Sal]

I'm currently running Windows version 2.5.1 and would like to upgrade
to 2.5.2. My question is, can I just go ahead and install the new
version over the old or should I remove the old version with add/
remove programs first? The old version is in a directory named
Python25.

You can do either. Since there's no change of major version the
executable will have the same path, and the deinstall handily leaves all
files that weren't part of the original install in place. So if it suits
your sense of neatness, by all means deinstall before reinstallation.

Note that this *doesn't* work for (say) 2.4 to 2.5, since they can
coexist. In that case normally the most recently installed version will
be the default. I had a Windows system a while back with 2.1 through 2.5
installed, and 2.4 as the default.

Steve

I would leave things alone unless you really want to start from scratch.
If you have installed any 3rd party packages that put files in
Python25/DLLs or Python25/Libs/site-packages, I would not trust the
uninstaller to not disturb anything.
