Abstract

A virtual process manager for use with a client application. Both the virtual process manager and the client application are installed on a client computing device. The client application is configured to receive a user command to execute a virtual application at least partially implemented by a virtualized application file stored on a remote computing device. In response to the user command, the client application commands to the virtual process manager to execute the virtualized application file. Without additional user input, the virtual process manager downloads the virtualized application file from the remote computing device and executes the virtual application at least partially implemented by the downloaded virtualized application file on the client computing device. The client application may comprise a conventional web browser or operating system shell process.
