怎么安装啊，我用DT装载ISO文件安装，但是它弹出3个对话框，分别是Before continuing with the installation process,please close all running programs.
Click OK to continue, or Cancel to quit the installation and exit running applications.
You must have a copy of The Battle for Middle-earth™II installed to play the Rise of the Witch-king.the installer will now exit.
再点就像他说的exit了，根本没法安装，这怎么办啊？
