I have installed the last release of Intel XDK on my Windows 7 Pro laptop. Download and setup were successfully performed, but when launching the software, the main windows is correctly displayed then a second windows, with an animated GIF 'Loading', appears and hides the main one during a part of a second before closing it-self. Then the 'Loading' appears again without end (I have waited around 30 minutes without change). I have also tried again to launch the Intel XDK without change. During this flip-flop, I observed a slow activity in the network.
