Hmm, so basically they are just now coming up with REALLY complicated ways to solve what ALL others have solved before them. And all in all the biggest part of the problem is that dll's still are named in 8.3 fashion. On Unix systems the version number is part of the file name, so you only open the right version, never one too old or too new... On AmigaOS a library can be put in PROGDIR: as well as LIBS:, and you can request specified limits on what versions can be loaded. My god those people at Microsoft are way behind.
Oh, and the whole thing about copying instead of reinstalling, I can't imagine why they didn't just shoot whoever designed the original system in the first place.
