How Can I add the Net Framework to my setup project?

[Husam]

Hi EveryBody : I did the follwoing procuderes but it did not work with me:
1- Make sure that the Visual Studio .NET Framework Bootstrapper Plug-in is
installed.
2- Select the Setup project in Solution Explorer. On the Project menu,
choose Properties.
3- Set the Bootstrapper property to Windows Installer Bootstrapper.
The .NET Framework redistributable will be packaged with the Setup.exe for
the Setup project when it is built.

Note The .NET Framework launch condition must also be enabled; it is
enabled by default for any project that references the .NET Framework. To
check for the launch condition, from the View menu, point to Editor and
choose Launch Conditions, then look for a launch condition named .Net
Framework.

So any one have idea how this work?

any help will be appreciated
