Home Theater Questions? Ask a Technician for Answers ASAP
Hello, Sorry you're having problems. I'm not sure exactly what app you were using, but perhaps it's the "Receiver AV" app below? Please check that out and if it's the correct one, do click a POSITIVE (3-5 star rating at the top of the page) for my efforts:
That one can download onto either a PC or Smartphone, and there are other Smartphone only apps for Denon, but I'm assuming you're strictly looking to use a PC as the controller?
Are you able to tell me if that's the correct App or not please?
If you need further assistance let me know. Before you go, PLEASE DO click at least a 3 STAR RATING, at the top of your screen. That is how I am credited for my efforts by the site. You can follow up any time as needed at no additional cost.
