Open the existing project in the Smarx Application Framework (SxAF), and choose the application you want to update in the tree view under “Applications”. Now click the button “Update Application”, select the new application you want to protect, and click “OK”. Then click the “Protect Application” button to protect and store the new protected application.
NOTE: Do not use the "Application Checksum" DataObject if you plan to preserve compatibility with further updates! Otherwise, an update of the CRYPTO-BOX is required (e.g. with Remote Update).
