By default, Cerberus is installed as a service with the “Interactive Service” flag set to true. This is a legacy setting and is no longer needed with version 3.1 and above. I’ve never had anyone report it as a problem before, however. Have you explicitly set some policy on your machine to not allow interactive Windows Services?
Regardless, I’ve modified the installer to no longer set the interactive service flag on service installation. Try downloading the latest installer and trying again.
