Well, the installer itself should provide the function for
removal/uninstall. If the installer doesn't find an existing
installation it should provide Install operation only. If it finds an
existing installationen, it should provide uninstall operation. If it
finds an outdated installation it should provide Update operation.
I know Maintenance tool does this, however I would like to avoid the
installation of additional maintenance tool. I would prefer the old-
school way... implementing the maintenance and deplayoment features in
the installer and the application.

So the Maintenance tool would take the application from the local disk?
But how to put the application to the disk after installer has been
Also the maintenance tool would still be installed (but with a useless
update function) wouldn't it?

What a pitty. Anyway, how can an offline update work without that
