To download and use your diagnostic and testing software, you need the Diagnostics Download Manager (DDM). Download the DDM one single time now. It will assign your specific software package to you.
The rest of the procedure is automated: The DDM regularly checks the availability of new updates for your diagnostic and testing software. You are free to decide whether to install the update immediately or later. While the updates are loading in the background, you can continue to use the diagnostic and testing software in the usual manner - automatically and always with comfort and ease.
