Well, tlpmgui v. 1.69 introduces --install-mode option to force 
installation, but it is not documented. I do not know where to put such
information (except, of course, tlpmgui's help).
Please note that for most windows users even starting such program
with an option is not so straightforward (they are just used to clicking
program name or icon). Again, guessing if the user has any existing,
or not completely unistalled, or perhaps broken previous TeX installation
it is not so easy task. So what more can be done? 
Please note also that most disputants here are in fact good system
hackers, but we have to think about ordinary, not so advanced users and 
they rarely have many TeX installations.
