All you need is an update to your hauptwerk usb dongle. This enables the advanced features. You don’t have to reinstall hauptwerk. I’m assuming you already have the current release (4.2.1.003) of hauptwerk installed. Perhaps the dealer / mda has sent the link to the software as in case you haven’t installed the latest version.
The instructions for getting the usb dongle update are at https://www.hauptwerk.com/forms/license-updates/.
