Thank you for your answers. Its all confusing at the moment. We need some good tutorials for mobile productions. At the moment I am not able to archive the quality with HTML5 which I need. I guess there are many ways to fake reflections, dynamic shadows and so on.
For example, 64 do not work at my system. Only the 32 bit version. With 64 bit I get errors or the download hangs and nothing happens. I do not understand this.
