The program should ask for rights elevation, perform some extraction, then start installing itself when run. Which of these 3 steps is it failing on? If it quits before rights elevation, you probably have a corrupted download. If it makes it past rights elevation but then quits, your temporary folder isn't writable. If it gets to the installing stage before quitting, odds are your Windows Installer version isn't new enough to install the program, or Windows Installer is corrupt, or Windows Installer isn't running because it's disabled in Services.
