An essential component used by Dorico for playback has not been found

Hi @malycknm , thanks, but first try something else:

  • Go to the Steinberg Activation Manager
  • Hold down the Shift key and click in the Refresh button in the Activation Manager (right top of the window).
  • Then wait for a few seconds until the spinning balls at the bottom of the window go away.
  • Then try again to start Dorico
