METHOD AND SYSTEM FOR STORING CONFIGURATION DATA INTO A COMMON REGISTRY

A shared registration DLL and configuration data files that are used by setup programs and their corresponding application programs to register configuration information in a registry and to un-register configuration information from a registry. The shared registration DLL simplifies writing and synchronizing configuration information registration routines in a setup program and in its corresponding application program. The shared registration DLL allows for specifying relative file system pathnames to the application and to application files, rather than requiring file system pathnames to be fully specified. The shared registration DLL allows for configuration information registered previously by an older version of an application to be stored in the registry when a newer version of the application is installed, and to be restored when the newer version is removed from the computer system. The shared registration DLL and configuration data files allow for incremental addition of configuration information to the registry when new components for a previously installed application are added to the computer system.
