Consider the following scenario. You develop an application that calls the CoGetClassObjectFromURL function to install an ActiveX control. On a Windows Vista-based computer that has ActiveX Installer Service enabled, a user who has the typical user rights and the typical permissions runs the application. In this scenario, you expect that the user can install an ActiveX control. However, the user is prompted to enter administrative credentials when the user tries to install an ActiveX control. Therefore, a user who does not have administrative credentials cannot install an ActiveX control.
