I try setup PreRequisites for .NET 4.0. I checked .NET 4.0 Redistibutable package and download this package.
Next I compile installer.
But when I run this installer on the machine without .NET 4.0 it tells me 4.0 is not installed but does not give me any option to install it. (It just will not let me continue with the setup).

What's wrong?
I expect it should offer install .net 4.0 on the machine without 4.0.

Thanks, Andrew
