Note An update for the .NET Framework 1.1, the .NET Framework 2.0, the .NET Framework 3.0, or the .NET Framework 3.5 will not install any detection registry keys as described in this table if there is a newer superseding update that is installed. In such a scenario, you should determine the newer update instead of the superseded update.
