VS Installer Solution warning errors: 'DLL file is under Windows System File Protection' during Compile

Question

I'm building an Installer Solution for a VS project in C#. During the compile process I get the following warnings:

Reading some related posts I beleive I should remove these dll's from the Installer itself, meaning from the Primary Output of the Installer Solution...? Is this correct or is the issue somewhere else?

A further question is - will this harm any functionality on a user's machine? Do all of these dll's exist on standard Windows and will work without being compiled?

Thank you
