You don't need to build a setup program to distribute your Add-in. Users can install it with the Add New... button of the Add-in Manager. When a user selects the Add New button, Microsoft Access brings up a standard file-open dialog box The user selects your add-in library database from a shared database on the network or from a floppy. The Add-in Manager opens the database and searches for a table named USysAddins. It contains records that tell the Add-in Manager how to install your Wizard from a network or floppy drive into a user's Microsoft Access directory. Then it makes all the necessary entries in the user's MSACC20.INI file to load your Add-in database as a library and register all the appropriate UI entry points. This alleviates your need to write a custom setup. Instead you can just ship a single .MDA file, and let the Add-in Manager take care of the rest.
