If we ask where it should be installed, then we need a registry setting for that
Right.
So I think that asking is not an option at all. It either goes in %PROGRAMDATA%\Python\zoneinfo or it's not shared at all.
If that works for all xp+ versions, fine.
I know where I would choose, and it would not be on my C drive. Un-installers would not delete (unless a reference count were kept and were decremented to 0).
True, and that's annoying when those counters go wrong.
It seems to me that Windows has a mechanism for this, at least in some versions. But maybe it only works for dlls.
All in all I would say I would prefer to install this per Python.
Then explicit update requires multiple downloads or copying. This is a violation of DRY. If if is not too large, it would not hurt to never delete it. -- Terry Jan Reedy
