This sounds like the second time you're installing you are not
installing something that has a different version from Windows
Installer's perspective. Remember that Windows Installer ignores the
4th version component. If during your upgrade testing you install base
version 1.2.3.4 and then upgrade to version 1.2.3.5, then Windows
Installer treats it as the same version and you get the repair
behavior you're seeing.
