I'm running on Windows 7 64bits with Unity 2017 and the latest version of the Vuforia plugin.
When i play my application with Unity, it works perfectly. I have a Logitech webcam (B525 HD).
When my webcam see my image target, i have a cube appearing on the Unity game tab.
I have built the executable file by choosing the platform "PC, Mac and Linux Standalone" on the Unity Built settings window.
But, when i run the .exe file of my application, i have only a black window.
My webcam seems not working.
I have also try to launch the .exe file on a Microsoft Surface Pro 3 with Windows 10 but i have the same problem.
I have a free version of Unity and Vuforia.
Thank you very much if you can help me.
