I have problem in starting Dues Ex game. When I try to start this game, it doesn’t starts and instead of that I get an error message saying “Unable to reserve 512MB of address space”. I restarted Steam and even my computer but that made no effect, and I am getting error message now also. My computer meets all the requirements of Dues Ex: Human Revolution. But, then also I am getting such error. I don’t have any idea what the problem could be. So I want you people to suggest me any solution for this.
