No Systems. No Parts!

This is how Dorico looks. There must be three systems to be seen. You can not see anything. Also from a template everything is only so displayed. I already have Dorico uninstalled and reinstalled, no improvement. Gold standard!

Can you provide a screenshot of Setup mode, with your chosen layout selected? It’s possible the layout you are displaying has no players assigned to it.

Indeed, you need to make sure that you have at least one player and one flow assigned to your layout, otherwise there’s no music for Dorico to display.
