The Plugins and components page of the application builder  lets you set each plug-in and each component that you will use in your  single-user or client-server application. For more information about 4D  plug-ins and components, refer to the Installing plugins or components section. 
The page lists the elements loaded by the current 4D application:

The Type column indicates the type of item: plug-in or component. 
The Active  column indicates that the items will be integrated into the application  built. All the items are checked by default. To exclude a plug-in or a  component, deselect the check box next to it. 
If you want to integrate other plug-ins or components into the executable application, you just need to place them in a PlugIns or Components  folder next to the 4D Volume Desktop application or next to the 4D  Server application. The mechanism for copying the contents of the source  application folder (see Customizing the 4D Volume Desktop folder) can be used to integrate any type of file into the executable application.
- If  there is a conflict between two different versions of the same plug-in  (one loaded by 4D and the other located in the source application  folder), priority goes to the plug-in installed in the 4D Volume  Desktop/4D Server folder. 
- On the other hand, if there are two instances of the same component, the application will not open.
Note: The use of plug-ins and/or components in a deployment version requires the necessary license numbers.
