When I download the game on my computer I have to opened with WinRar and it's not free. There's another way to opened that is free??
I use 7zip instead of winrar and it's free.
Also Windows has a built in software that will extract files too. In your downloads folder, if you left click on the file in the explorer window, you should see an "extract" highlighted up in the top of that window. If you click just under that you'll see it says "compressed folder tools". If you click that, you'll see "extract all" pop up.
