Abstract: Systems and methods are provided for application software system installation in a user device wherein the desired App includes App configuration data to be entered by the intended user through a user interface. An App configuration data validation processor verifies that the user has correctly entered the desired App configuration data. When the user requests an install of the desired App to a particular device, the system digitally signs the App with the validated embedded data in an App configuration file, which digital signature must be validated by the intended device before installation of the App is accepted on the device. After both validation of the configuration data and the digital signature, the user is then permitted to execute the App on the intended device.
