I might be am wrong, but surely any tool that performs cleanup in a
user's profile needs the user's login credentials in order to load their
profile.
How are you going to get those?
msizap only removes the msi database side of the application (i.e.
component and feature registration).
It does not uninstall the application's files, registry keys, services etc.
