Allows your QuickPatch project to override a previous patch installed on the system. Typically setting this value is not required, even when you have several QuickPatch projects in the History view. However, if your QuickPatch project does not overwrite files added in a previous QuickPatch project, it may be necessary to populate this field. Enter the GUIDs of previous patches that you would like to replace, separating each GUID with a comma. For example:

{C86838C9-DEDC-4451-B96F-94AFB9460F15},{C8633E5B-AC44-45d8-B487-C68B3B1F60D6}

If you do not know the Patch GUID that you want to replace, click the browse (...) button, browse for your patch (.msp or .exe), and the proper GUID will be added to this field.
