Carlos,

Thanks for the question. If you are JUST playing the Falklands War: 1982 (not The Falklands War installed on top of Armored Task Force and or Raging Tiger), you ONLY need upgrade version 1.22.

(If you have no idea what I was talking about when I said, "installed on top of" then you only need version 1.22, too)

Patrick, thank you very much for your response.
My original language is the Spanish, therefore my English is limited enough.
For such a motive, probably I did not do well the question.
Yesterday, I discovered the game and when I wanted to install it, met 2 versions: version demo 1.12 of 15.8 Mb and version upgrade 1.22 of 3.7 Mb.
My doubt is if I must install the demo only ó if I must install also the upgrade.

I wait to have been clearer and apologize for the inconveniences that I you can cause.

A cordial greeting
Carlos
