Microsoft Installer (oops, now Windows Installer) implement this
"natively", and I assume most MSI-based generators/packagers support
it.

AFAICS it would require quite a few enhancements (and modifications to
the user scripts) to abstract away per-machine vs per-user
declarations in InnoSetup.
FWIW since InnoSetup is scriptable it seems one can implement this
manually using a few hacks:
