The "retry" dialog isn't just shown when files can't be replaced, but
when files (i.e. dll's) are loaded in a process. On XP, those dll's can
still be replaced, but the already started processes which have that dll
loaded will keep using the 'old' dll. That's why the dialog asks you to
close those processes so that they can start using the new dll.

A reboot is not recommended by msi, but forced by us explicitly. We
ourselves force the installer to ask for a reboot at the end. That's
because it would be dangerous if we have a change in the communication
between the shell dll and the cache process. If you don't reboot, the
explorer/desktop will keep using the old dll, but the cache will be
running with the new version. This could lead to crashes if the
communication protocol doesn't match.

To avoid any (even if they're unlikely to happen) crashs, we force the
reboot prompt at the end.
