After an Application has been installed using a Version Installer file, it can be patched by a compatible Patch Installer file.
As a Patch install does not support the full functionality of a Version install, the number of dialog is considerable reduced and do not allow any input related to configuration.
Note: Versions consist of a three part number, for example, 1.22.333 and Patches use a four part number, for example, 1.22.333.4444, which relates to the Version the Patch is based on. It is also important NOT to rebuild a Version after it has been released and installed as any subsequent Patches will be incompatible unless they are also rebuilt and re-released using the set of GUIDs generated for the Version. Microsoft Windows Installer technology will enforce this relationship.
