Abstract: Software is updated via a self-contained executable that includes software update patch for updating pre-existing software, and an updater package including at least one predetermined required computer state condition. Executing the self-contained executable on a client computer includes investigating a state of the client computer, and determining whether the state of the client computer matches the at least one predetermined required computer state condition. When the state of the client computer matches the at least one predetermined required computer state condition, the software update patch is installed. When the state of the client computer does not match the predetermined required computer state condition, the installation is terminated or, alternatively, the client computer is forced into a state that matches the predetermined required computer state condition and the software update patch installed.

Abstract: Methods of software updating via a self-contained executable are disclosed. The self-contained executable may include a software update patch for updating pre-existing software, an updater package including at least one predetermined required computer state condition, and a package processing engine. Executing the self-contained executable on a client computer may include investigating a state of the client computer, and determining whether the state of the client computer matches the at least one predetermined required computer state condition. When the state of the client computer matches the at least one predetermined required computer state condition, the software update patch may be installed.
