The installation program does not start

I downloaded the launcher for combat arms classic, I downloaded the game and when I press on the installation file nothing happens. Every time I try again nothing ever happens. What do I have to do?

CombatarmsClassic_installer I downloaded. But installation not happening. Does not react.
