What is the proper procedure for updating this app?

[RobCom]

Add/Remove programs uninstall, OR, running the new installer over the old one, OR, running the new installer and it will automatically uninstall the old version??

Thanks

Hi Rob,
Either method is fine. Running the installer again prompts the same uninstall routine as doing it from the add/remove programs list.
What I would say is that I'd recommend manually deleting any left over aircraft files from wherever you installed them. Files/folders that have been added/updated since the install can sometimes be left behind.
