Is there a common 2.0 SP2 .NET?

I am a bit confused about .net "distributed" "...".

Our C # code uses some API calls that require .net 2.0 sp2. We don't want the user to download anything during installation (it's a Winforms app and installer) for various reasons. We are currently including redistributable versions 2.0 and of course features that require sp2 throws.

Is there a redistributable package for 2.0 SP2 somewhere?

If not, what would be the best alternative?
