  • You seem to be under the impression that you replaced earlier frameworks when you installed .NET Framework 4.0. That is not the case. The different framework versions are designed to work side by side on a computer.

    Further, if you have Windows 7, Framework 2.0/3.0/3.5 (this is a single framework. 3.0 and 3.5 are extensions of 2.0) through 3.5 SP1 are integral parts of the OS. Vista includes 2.0/3.0.

    So, tell us which Windows version you are using. You are being offered the updates because you *do* have .NET 2.0/3.0/3.5.
