了半天，终于成功进入游戏了，经测试，战役和单人场景都可以玩。以下是我的解决方案:

一、注册表：

网上流传的注册表中只有埃拉西亚的光复和末日之刃的键值，这就导致了在64位系统中打开死亡阴影的战役会卡死，解决方案是加入死亡阴影的键值，完整的注册表如下：

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\Wow6432Node\New World Computing\Heroes of Might and Magic?III]

[HKEY_LOCAL_MACHINE\Software\Wow6432Node\New World Computing\Heroes of Might and Magic(TM) III Armageddon's Blade\1.0]

"AppPath"=".\"

"CDDrive"=".\"

[HKEY_LOCAL_MACHINE\Software\Wow6432Node\New World Computing\Heroes of Might and Magic(TM) III The Shadow of Death]

[HKEY_LOCAL_MACHINE\Software\Wow6432Node\New World Computing\Heroes of Might and Magic(TM) III The Shadow of Death\1.0]

"AppPath"=".\"

"CDDrive"=".\"

二、兼容性：

兼容性请选择WIN98

三、以管理员身份运行：

其实仔细一看上面的注册表就会发现，英雄无敌的游戏配置的设定（音量大小，音效大小等等）是写在注册表中的，所以如果不用管理员身份运行的话，游戏进程就无法修改注册表进而导致出错。

四、其他：

如果在64位系统中已经运行个老的注册表文件11.reg，那么需要把添加进去的那些键值都手动删除后再运行新的64位注册表文件。
