I realise this is an old thread, but having just picked up a NevoSL I've been fighting Nevo Studio on my Windows 11 machine! I found a thread here to make it work on Windows 10, and that worked, I have it running now :)
I haven't tested stuff extensively as I'm still waiting for my SL to actually arrive BUT - in terms of registration - if you add key DigitalSignature to the registry it stops the registration window from appearing every time you open Nevo Studio!
I uploaded here

Windows Registry Editor Version 5.00
UserName string is base64 encoded. "ZW1haWxAYWRkcmVzcy5jb20=" decoded is simply "email@example.com"
If you don't want to download just add this manually:
and add new string
Since that alone stops the reg wizard showing when opening.
