the installation of a pre-3.3 version of Python after Python 3.3 is installed with the launcher will, if the user selects "Register Extensions", hijack the laumcher's associations to that earlier Python. Then bye bye launcher

I don't see how anything can be done about that. It also doesn't seem like too serious a problem -- it's no worse than what currently happens if you install an older version over a newer one, i.e. associations revert to the old version.

Making the launcher a separate install at least offers a way of fixing that if it happens and isn't desired, i.e. reinstall the launcher.
