The version-dependent file installation option ensures that a previously installed version of a file on the target computer is overwritten only, if it is older than the file to be installed. For this mechanism to work the file must have a version ID assigned. The Installer checks the internal version ID of the file during installation of the product on the target computer.
All product files with an internal version ID are automatically assigned the version-dependent installation option. All .dll and .exe files generally have a version ID.
To specify the version-dependent installation option, select the appropriate file path name on the Product Files Filter tab of the Configure Reference System dialog and click the version-dependency button.
