Question

我无法让Internet Explorer或Windows资源管理器加载此BHO。当然没有可以创建的COM对象，但是在加载DLL并检查之前，Explorer无法知道，但LoadLibrary没有被调用。

当我运行regsvr32时，会显示消息框。

Windows版本= 8.1

Internet Epxlorer Version = 11

开启或关闭增强保护模式似乎没有什么区别。

对于增强保护模式（EPM）中的IE11，必须使用以下命令更新注册表：

HKEY_CLASSES_ROOT \ CLSID \ {您的BHO CLSID} \已实施分类\ {59FB2056-D625-48D0-A944-1A85B5AB2640}

BHO对象不会加载，可能是注册麻烦？
