Registering your plug-in by entering your license information in the plug-in configuration screen will sometimes fail due to permission issues (i.e. forgets the registration or cannot create registration) file on the installation computer. When this happens, typically it can be resolved by logging in with an account that has administrative permissions and then conducting the registration.
However, in cases of a networked computing environment that uses centralized authentication and application servers, there can still be problems with the permissions that prevent the plugin from storing and retrieving the necessary license info. The best resolution in such a case it to register the plug-in by using the plug-in’s built in registration function call.
From a startup script in your database, simply call the plug-in with the registration function and pass the necessary license code parameters. That way every time the database is opened the plug-in will be automatically registered.
