We have more than one installation with shared/non-shared files. I'd like my Major Upgrade to do not leave any old version files on a system, i.e. to uninstall the previous version of it's own installation and uninstall other old installations (which have different upgrade codes of course) as well. Is this doable? Searched through the forums and did not find much.
I just experimented with two installs - defined one "sharing my Upgrade Code" and another "another Upgrade Code" - non of old installs were uninstalled, the new one got installed, checked reference count of some files - all three are there. Log file mentions only "my upgrade code", does not mention another one and does not report any errors. Are you sure that scenario actualy works?
I'm now simplifying my test - removed "another" Upgrade record and trying to Upgrade just "my Upgrade Code" and that seems to be working, so my setting are correct.
