The present invention provides an interactive graphical user interface (GUI) patch environment for installing a patch on the targeted systems. A system administrator or other authorized user interfaced with a machine may perform the installation of a patch on the machine using a software wizard. Additionally, the Wizard pre-verifies the patch dependencies (pre-installed software) required by the patch and checks the target systems to ensure the target systems possess the requisite dependencies. Once the target systems have been validated and the required dependencies identified on the target systems, the sequencing algorithm sorts patches in correct order before applying patches to the target systems. The user can remove the patch from the pre-validated patch list about to be applied to the target system. The patch dependency is checked before removing the patch from the pre-validated patch list for proper removal order.

Pre-verification and sequencing of patches

A system and method of installing a software patch on a selected electronic device using a graphical user interface is disclosed. The user utilizes a graphical user interface (GUI) to select a patch to install and selects an electronic device, the 'target' device, upon which to install the patch. Patch dependencies on the target device are programmatically determined and checked to ensure that software required for the patch is present on the target device. The installation of the patch is then performed. The illustrative embodiment of the present invention also enables the removal of a patch from a targeted device following a determination of which applications on the target device are dependant upon the patch, and subsequent user authorization of the removal operation.
