All add-ons installed on an organisation's system are available for the System Administrator in the System Marketplace. Navigate to System Marketplace in the System Admin panel to find all add-ons listed in the system. Installation of add-ons for other users or groups can be handled by users themselves in the Marketplace. To install a system add-on, select the system add-on to install and complete the installation procedure. In the System Marketplace, add-ons can also be approved for installation.
Installing a system add-on makes the functionality of the add-on available for all users in the system. Users will not be able to uninstall this add-on. Once an add-on is installed on the system it appears under the installed tab in the Marketplace.
