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!


Download NevoStudio.reg I uploaded here and just double click it and say YES to enter it into reg.

Contents of file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\UEI\Nevo\NevoStudio\Settings]
"UserName"="ZW1haWxAYWRkcmVzcy5jb20="
"UserProfileID"="123456"
"DigitalSignature"=""

UserName string is base64 encoded. "ZW1haWxAYWRkcmVzcy5jb20=" decoded is simply "email@address.com"

If you don't want to download just add this manually:
Goto: HKEY_CURRENT_USER\Software\UEI\Nevo\NevoStudio\Settings
and add new string
"DigitalSignature"=""

Since that alone stops the reg wizard showing when opening.
