這個問題很好解決，需要兩步。

一、注冊表文件導入

32位的Vista或者Windows7甚至XP系統，玩綠色版的魔法門英雄無敵III的時候，需要雙擊一下英雄無敵所在文件夾下面的一個 .reg 文件，一般是 11.reg 或者 其他名字的 .reg 注冊表文件。雙擊這個注冊表文件，導入到系統注冊表，綠色版就可以玩了。

但是，64位的XP、Vista、Windows7系統下，導入這個 reg 文件，也沒法玩，原因是，reg 文件里面的鍵值，需要更改一下。

在 reg 文件上面右鍵，編輯——

二、管理員權限

XP用戶不用看這個了，32或者64位的Windows Vista、Windows7用戶，把要運行的Heroes3.exe 或者其他名字的主程序，右鍵一下，點擊“以管理員身份運行”即可。否則，可能因一運行，就跳出如下對話框：

三、如何用窗口模式運行英雄無敵3

如果要用窗口模式而不是全屏模式運行英雄無敵3，需要把你的顯卡分辨率桌面色彩調到16位色狀態，運行打開英雄無敵3之后，按下F4鍵。或者在快捷方式的屬性的”目標”中修改如下：注意exe和-Windows間有空格：X:/Heroes3/Heroes3.exe -windows （前面的是你的游戲文件夾路徑，自己根據情況修改）。

這種方法，適合所有的32和64位Windows系統，大家可以按照辦法去做，就可以了。

順祝大家玩的愉快。
