[issue24585] Windows installer does not detect existing installs

[Steve Dower]

New submission from Steve Dower:

If you have Python 3.5.0b2 installed and run the Python 3.5.0b3 installer, it will upgrade correctly, but gives no indication that it will remove the old one.

We should default to an upgrade using the same settings as the previous installation when one exists. Users can then hit Customize to change settings if they want, or uninstall the old version to do a clean install.
