Follow these directions:
Run the installation file. Then go to ALL APPS in Windows and in the Ashampoo folder you will see the ASHAMPOO CONNECT link. Launch Connect and, for me it first updated. Once updated you see a list of Ashampoo apps. I then relaunched the original download and the Ashampoo Connect now displayed the Music Studio 2024 app. Click on the install and you are good to go. You will notice an install dialog along the way that asks for a rating and below that is a bar labeled KEY. Click on that to copy and save the key for future reference if desired. You do not have to manually enter the key during the initial install.
