An activation control apparatus stores first association information that associates, for each application, application identification information for identifying an application with terminal identification information for identifying a communication terminal permitted to debug the application. When a first communication terminal is provided with a debugger, the activation control apparatus determines whether any candidate application available for use by the first communication terminal is associated with terminal identification information of the first communication terminal using the first association information, and excludes from the candidate applications one or more applications that are not associated with the terminal identification information of the first communication terminal to generate an application list of one or more applications that can be activated. When the first communication terminal is not provided with a debugger, the activation control apparatus generates the application list that includes all of the one or more candidate applications as applications that can be activated.
