Vvvv just does not work on my PC

I am new here and trying to download vvvv and open it. As I have followed the download page. The vvvv just does not open on my PC. But it works on my laptop. So I am wondering why ???

have you run setup.exe and made sure all lights are green by installing the necessary components from the button next to the red lights?
