Another Installer/Setup Project drama, .NET 3.5 required but .NET 4 is installed

Rather simple thing, but took me a fair bit to solve this one. Maybe cause I am blind.

Had  .NET project create with target framework 4. Changed them to 3.5.

In installer/setup project changed .NET framwork to 3.5 also changed link.

If I clicked on setup.exe it still would dl .NET Framework 4.
Go to Installer/Setup project properties. Click on prerequisites and select what you need.

Simple ehhhh 🙂
