The TemplateSetup entry is used to determine if certain databases (for example, Log, Address Book, MAIL.BOX) should have their design updated as part of the install. The TemplateSetup entry is then set to the new value to ensure that database design changes only occur once.
Tip:
Close Lotus Notes, Change the notes.ini value for TemplateSetup=xx to TemplateSetup=0 Start Notes again, this forces an update of all local databases such as bookmarks, contacts to the latest installed version (as long as the templates are accessible!)
