[RESOLVED] Query in SQL Server instances and registration

It seems I have successfully created another instance of SQL Server in my computer (I have looked into it in the Program Files folder) but cannot create a registration for it, what am I doing wrong? Just wish to have two registration to test some functionality and I thought creating another instance would help but I'm having trouble... :(

What happens when you try and create the registration dee?

It seems to tell the server does not exists... Is it possible to create a registration for another instance?

Got it now, I had to use Mixed Mode so the service of the other instance could start and be registered...
