ArcGIS for Desktop has a set of optional extension products that you can install and work with. Each adds a set of specialized and advanced capabilities to your geographic information system (GIS).
Enabling extensions for ArcGIS for Desktop
To add the capability to use any extension, ensure that the extension software is installed on your computer and that you have added keycodes to unlock the use of the software on your desktop. See Adding additional installation features for more information on how to add extensions.
Next, enable the desired extension using the following steps:
