when you install this you need to paste this into the portal folder or int to the portal folder within your portal folder. for me my games are in my common folder so I would paste this into
"C:\Program Files (x86)\Steam\Steamapps\common\portal\portal" if it doesn't affect files out side of the portal file inside your portal file. don't paste it into your "modsource" folder.
