Abstract: Systems and methods for creating application runtime environments or application environments that can be downloaded and integrated into the computing environment of a computing device are disclosed. One embodiment of the invention includes a computing device on which an operating system is installed that creates a computing environment, an Application Platform application, where the Application Platform application is at least partially natively implemented and creates an application runtime environment when executed by the computing device, and a cross-platform application, where the cross-platform application is configured to be executed within the application runtime environment and is not natively executable by the computing device. In addition, the Application Platform application is configured to integrate the cross-platform application into the computing environment of the computing device by providing at least one launch point for the cross-platform application within the computing environment.
