ArmA: Armed Assault Installation Problem

[Skyfox117 1]

My older brother gave me his unopened copy of ArmA for me to install, so i've put in the disc and started the autorun installer, it will procede with each step then will start to install. It will get up to "characters.pbo" then the ambient music will stop and it will not procede in installing. I have left it installing for 5 hours and have tried this twice, what can I do?

Does your computer meet the minimum specs? Do you have the required space available?
