Currently, I think, the installer doesn't offer to uninstall the
previous version, although I have only tested it on wine. I would have
assumed it did.

So, we have an half-and-half world at the moment. It doesn't install
multiple versions cleanly, nor does the "update to a new version"
functionality work cleanly. You have to uninstall the old one first.

None of this will result in an unfunctional Emacs, so it's not a
disaster. But I think it should do or the other.
