Please give more information. What happens when you download Roon for Windows from the Roon Labs download webpage and try and install it or your replacement PC?
That may well be so. But I cannot use it because it says I have another instance running and I must shut that down first. But I’ve lost/misplaced the laptop, so can’t do that!
So if you’re seeing an Unauthorize button on the Roon screen, just click it to unauthorize your old Roon Server and transfer the licence to your new one…
