I do, and I've never tried not to.  I don't know what would happen if you
don't.  Why risk it?  The PLabs Windows installer certainly doesn't
uninstall older versions first.

No, and the PLabs uninstaller for 2.2.2 won't remove them either, so it's
safe to use that to uninstall 2.2.2 first.  The 2.2.3 installer will note
that the installation directory already exists then, and ask you whether you
want to install 2.2.3 on top of it.  Say yes.

Note that the answer is different then when you move from Python 2.2.3 to
2.3 -- in WindowsLand, Python releases are not compatible across minor
version numbers (the second digit in i.j.k).  That's unique to Windows, BTW
(on Linux, e.g., you'll probably be able to use 3rd-party binaries compiled
for 2.2.3 with 2.3 too, but never across a minor version number increment on
Windows).
