| - A COM component needs to be registered in the registry in order to be used. In case of an Inventor COM component the registration needs to have some extra properties so that Inventor can see that this is an AddIn
| - When Inventor starts it checks the COM components and their properties. If the appropriate properties is added to the COM component’s registration, Inventor will load the component and will call its Activate function where the AddIn can create the framework of its functionality – so it can create the buttons or other User interface elements for the user, and can also apply for various Inventor events.
