So, all you need now is a very old game. See if you can buy the game on ebay where someone is selling his game. Ask him if the game he is selling is lower than 1.09 and buy it. But buying a second hand copy is always a risk.
I think the full game, wether it is 1.09 or not, will not run decent on your laptop at all. Arma and laptops are just bad combinations.
