How long does it take to download combat arms to laptop

It depends on your internet connection, for example, with my intenet connection, it would take about about 12 minutes, because my internet download speed is about 750kb/s and the download it approx 500mb. Try downloading something small, go to Google and type in '7zip download', download it and see how fast you get, then divide 500000 by your internet speed, that how many seconds t will take you, then divide that by 60, and that's how many minutes it will take you.
