2、将下载的文件放入到你要运行的软件或者游戏的安装所在文件夹之中，可以右键点击主执行程序.exe然后选择"打开文件所在的位置" 找到安装目录，将文件复制进去。
或者将文件复制到Windows系统目录，这个需要注意电脑的系统是32位还是64位，如果是32位的系统，那就将本站下载32位的dll文件放到“C:/Windows/System32”这个文件夹里面,
如果是64位的系统，那就将本站下载的32位dll文件放到“C:/Windows/SysWOW64”这个文件夹里面,本站下载的64位文件放到“C:/Windows/System32”这个文件夹里面.
如果问题依然无法解决，值得注意的是此类文件的丢失有时候和杀毒软件的误报毒有关，所以请将此类dll文件添加到杀毒软件的信任列表当中.
二、使用本站提供的软件进行自动修复
