Why won't my Titanfall2 launch?

[ThePwnrMan69]

So I bought Titanfall 2 from steam and when I installed it and hit play my origin client opened and it shows a message that says "ERROR LAUNCHING GAMEThe game Titanfall2 Deluxe Edition does not appear to be installed. Please install it or try relaunching the game."

The game is already installed, I have seen where people say that you get a message to link your Origin and Steam accounts and that never showed up for me.
