如何在未安装Visual Studio的计算机上使用MSHTML？

I am using mshtml to parse HTML in my ASP.NET-MVC application. Works great on my development machine, which has VS2008 Professional installed. Works great on my staging machine, which has VS Express 2008/WebDev installed. But it throws a FileNotFoundException when trying to load the COM object on the production server, which has no versions of Visual Studio.I am using mshtml to parse HTML in my ASP.NET-M
