I need to allow an ActiveX (.cab) add on so I can remotely view my home security DVR. Windows will not allow me to install this add on because the publisher is unknown. I am running Windows 7 home premium whch unfortunately does not have group settings. I think I need to edit the registry in some way to allow this add on but I have not been able to figure it out. How can I configure Windows 7 Home premium to allow ActiveX?
