Allows you to register an add-in, load or unload it, and set its load behavior. If you close only the visible portions of an add-in — by double-clicking its system menu or by clicking its Close button, for example — its forms disappear from the screen, but the add-in is still present in memory. The add-in object itself will always stay resident in memory until the add-in is disconnected through the Add-In Manager dialog box.

To open the Add-In Manager, Add-In Manager from the Add-Ins menu.
