I have XP Developer and have built and packaged an application , now I know in the future I will have some updates that need to be added to the existing application , ie new tables , new forms , some forms being replaced with updated versions etc. Is it possible to make an update application within access and install package with the packaging wizard ? This being done of course without disturbing the existing data in the other tables . I plan on selling my application and want to sell some of it as add-on modules via the above methods , is this possible via Access or do I need to use stricly VB for this ?
