How do i fix this?

Ok so I am using 4.9.2 and still getting the automation tool unable to run… Can not find this UE4.sln anywhere on my computer. I have Visual Studios Community 2013 and I access my stuff through the Epic Launcher. I only have 2 levels to package 1 is the front end and the second is the main level. How do i fix this???

Never mind. I am missing something on my home computer to build stuff. It worked fine at school.
