我正在尝试在IE 11-Win 10中以“增强保护模式”运行测试BHO。
BHO所做的只是发出警报，“ hello world”。
我已经使用“任何CPU”构建了该库。
我确保我已写入注册表并使其可写（请参见页面下方的完整课程）：
var registryKey =
Registry.LocalMachine.OpenSubKey(BHO_REGISTRY_KEY_NAME, true);
if (registryKey == null)
registryKey = Registry.LocalMachine.CreateSubKey(
BHO_REGISTRY_KEY_NAME, RegistryKeyPermissionCheck.Default);
我已将库放置在Program Files的子目录中。
我运行了一个.bat文件，该文件使用x32和x64 Regasm注册了该库。
当那行不通时，我尝试的另一种选择是专门为x32和x64构建该库。然后同时注册两者。
我花了很多时间对此进行研究（我在这里阅读了所有看起来与远程相关的文章），但我不明白自己在做什么错。
为了公平起见，我在这里找到的适用于Win 8和Win 7的可行解决方案。要明确地说，我无法使其在“ Win 10”环境下工作。我可以在“ Win 7”环境（我没有Win 8）上使用相同的代码。
我很拼命，任何帮助将不胜感激！
适用于任何CPU库的Install.bat：
@echo off
:: Register
SET SYSPATH=%SystemRoot%\Microsoft.NET\Framework\V4.0.30319\RegAsm.exe
%SYSPATH% "%~dp0\IEExtension.dll" /unregister
%SYSPATH% "%~dp0\IEExtension.dll" /codebase

* The IObjectWithSite interface provides a siting mechanism. This interface should only be used when IOleObject is not already in use.
* By using IObjectWithSite, a container can pass the IUnknown pointer of its site to the object through SetSite.
* Callers can also get the latest site passed to SetSite by using GetSite.
