I live the same problem. Game path is very short, no unwanted symbols, JRE latest version installed.
(I use Windows 7 professional 64-bit sp1)
Did you try to install previous versions?
I can advise you to delete the installed version JRE. This is already included with the game, it should be work
Maybe something is wrong with the OS. I just never met such mistakes that the game did not react at all to the launch.
You may need to put in the properties "run as administrator"
