Sorry to hear you are having issues; I did work through that guide step by step as cleanly and clearly as I could.
So without any logs it is hard to say, Launcher Logs, Client Settings.cfg and DXdiag Log will go down a treat... and also last case scenario your swtor.exe (retail) log *"Remember to blank out your Login Name if you do post that log.

There is a picture of my folder. I do not have the swotr.exe retail app.

Heres a pic of what I mean by what i see on the launcher. I've circled it in red.
Where would I find clientsettings.cfg and DXdiag log?
1st image you have only installed the Client, the retail swtor.exe doesn't exist yet as per my guide at the top.
2nd Image very much confirms that you have not quite mastered the first part of the guide and all the things you have to do prior to actually running the Launcher.
Client_Settings.cfg is not going to be your problem here/yet as you clearly have not reached that part.
When you do simply click Windows Key + R and type %appdata% ENTER.
Navigate back to your Appdata, then Local ... scroll down to Swtor.
Again all of this is in the guide above.
