setup.exe wizard file creation

Question

I have a couple of projects done, but now I need to produce a setup.exe/wizard to manipulate where these files go via a setup.exe program.   I'm continually surfing the Internet attempting to find tutorials that would teach someone how to build a setup.exe program, in C#. All I get is youtube video's that goes by quite fast when clicked on.  Are there tutorials that say this and then tells why it was done.  I have two projects that I have to merge together and tell where each package goes.  I supposedly have a setup.exe C# program put together that emulates a video, but there are so many left unanswered questions on the whys of if all.  Is there a mentor program, somewhere, that helps teaches and help understand and mentors someone in a particularly intense field.  Any help sure would be appreciated,  Thanks.
