Are you talking about adding a "hyperlink control" to a dialog which the user should click to download the framework manually? Or should your setup automatically download and install the framework if it doesn't exist on the target machine?
In the first case: I don't think there's a hyperlink control. Also, installing the framework from within your MSI setup isn't possible (because the framework uses MSI itself). So you would need to create an executable that would download and install the framework and then launch your msi setup.
In the second case: InstallShield's setup.exe can do this for you. That's what "setup prerequsites" are for. Version 12 doesn't include a pre.build prerequisite for .NET 3.5 so you would have to build your own prerequisite using the prerequisite editor (or upgrade to InstallShield 2009)
