rc1 created a versioned dir name, rc2 doesn't. Based on this and bug#5506 I
think you're using rc1 and not rc2 -- I just relaunched the windows installer
and it says Sep 30, 2011, and doesn't have the 2.0 text.

Re: frankenstein scenario, this isn't an issue for the mac, the old dir is
first wiped.

On windows it currently is (I was under the mistaken idea it wasn't). IzPack
says it will "possibly overwrite" existing files. I've just run an experiment:
renamed my Kepler-2.2 to Kepler, and then installed 2.3. This leaves the 2.2
modules in place in the Kepler app dir. This is good on the one hand, wrt not
having to download these modules again. However it's bad in others, it makes
the windows and mac install behavior even more different, and when I launch
kepler after installing 2.3, 2.2 comes up -- there must be another MM bug here.

A few possibilities come to mind:
I can revert to including the version number in the name. We then lose the
benefit of getting rid of the MM GUI having to come up when starting old app
versions due to missing module errors.

I can look into having IzPack delete the app dir before installing. I'm not
clear on if this is supported. I see a request for it in 2005, but in a quick
look at the izpack issue tracker haven't found info on it.
