Build in Unity does not recognize Oculus

Hi!

I use Unity 5.2.2, with OculusRift DK2 (08. runtime version) for create a scene. In play mode, the Unity recognize the OculusRift with direct mode, and its works fine. But when I made an executeble build, it does not recognize the HMD. When I start run the build, I have to choose among "Display 1 (right)" ande "Dsiplay 2 (left)"... The Rift's indicator LED is always orange. Anyone has an idea?

Thank yo very much!
