Says Launching Blizzard Launcher but nothing.

I am trying to install the beta but everytime I run the Diablo 3 beta setup it goes through the updating setup files and then says lanching blizzard launcher but then nothing happens and it does not load. I also checked if I had a blizzard launcher or anything like that in processes and nothing. I have also multiple times deleted my C:/programdata/battle.net folder and even renamed the agent folder inside of it agent.Temp like some have recommended but none of these methods work and the same thing happens. Can anyone help please? Have also been opening it in administrator still no luck.
