To make sure the native client is accessible, click on the "Check Connection" button. If you still get this page even when the "Check Button" reports successful connection, it means the application cannot be accessed (path is not correct in the options page). If the path to the executable is correct and the native client is connected, you can debug the connection by enabling console logs.
