I had a computer stolen recently with Cubase 12 installed and active. I deactivated it from mysteinberg online. Will this keep the thief from using Cubase or will it automatically reactivate when opened?
More important than a thief using Cubase: have you changed your passwords? If not, that is the first thing that you should do (and I mean all passwords, not only the Steinberg ones). If you don’t do that, the thief could definitely reactivate the license with the Activation Manager, but I assume as Cubase does not “phone home”, the license is valid on that computer anyway.
All passwords have been changed. That was first.
If they do any form of system modification the SAM may ask for them to reactivate C12 and if they can’t gain access to the SAM then it’s deactivated
And, if they run the Activation Manager the license with be deleted from the computer since SAM is not logged in.
So really, as long as you put in place things like the two step varication on your Account then the new system is pretty safe
