Heureka!
The problem was my grafic card!
From Faro knowledge base:
"SCENE requires a graphics card that supports OpenGL 2.0 or higher. If your graphics card supports older versions only, the 3D view might not work on it. Switching off the advanced textures and/or offscreen rendering under Tools > Options > View might solve this. When switching off advanced textures, the stereoscopic view is not available anymore. When switching off offfscreen rendering, the stereoscopic view, the clear view and gap filling are not available anymore."
