Basically you are right (though in this case all what you pointed out does not apply). But it makes me think that this is a serious problem for any installer. I mean if someone wants to sabotage an install, all it has to do is to place bogus exe files, with the same name as the installed ones in the same locations and the installation will fail with no error! Because the new files will not be copies over and the ones existing can be of any origin and intent and none will notice until it is perhaps too late.
