Error launching Unity Player: failed to load dll

I am trying to play the Attack on Titan Tribute game (found here: http://fenglee.com/game/aog/) and whenever I try to play it says: Error launching Unity Player and the error details say "failed to load dll" I have tried re installing Unity Web Player and launching chrome as an admin but nothing works. I am using a Sony Vaio with Windows 7. This is my first time using Unity Answers so please tell me if I am using it wrong.
