I'm trying to install it in the way that is suggested but when it launches, the VM screen appears for a second or two, then an error box flashes and disappears (I can't see what it says) and I'm at a new prompt to create a VM.
I've downloaded the .ipsw again, from a different system, restarted Parallels, restarted my Macbook Pro (1 month old), but nothing works.
I'm running Parallels 27.0.1 build 58670
