我有一个从ASP.NET站点打开word文档中的一个问题。该解决方案工作正常的Windows 2003 Server上，但不能在Windows 2008服务器的x64和Windows工作7 x64的。

I have a problem with opening word document from ASP.NET site. The solution works fine on Windows 2003 Server, but doesn't work on Windows 2008 server x64 and Windows 7 x64.

要简化我创建了一个ASP.NET MVC 3的网站上的解决方案，并尝试从那里打开的Word文档。

To simplify the solution I've created an ASP.NET MVC 3 site and try to open word document from there.

环境，我有：Windows 7的64位和MS Office 2010 64

Environment I have: Windows 7 x64 and MS Office 2010 x64

在code打开adocument如下：

The code for opening adocument is the following:

    public ActionResult WordTest()
    {
        var fullFileName = @"C:\inetpub\wwwroot\fpub\TestDocument.docx";
        var impersonation = new ImpersonationManager();
        impersonation.Impersonate();
        try
        {
            var application = new Application();

            try
            {
                Type documentsType = application.Documents.GetType();
                var document =(_Document)documentsType.InvokeMember("Open", BindingFlags.InvokeMethod, null, application.Documents,
                                               new object[] {fullFileName});

                try
                {
                    return View(new ModelData {Result = document == null ? "Bad" : "OK"});
                }
                finally
                {
                    if (document != null)
                    {
                        document.Close(false);
                        Marshal.ReleaseComObject(document);
                    }
                }
            }
            finally
            {
                application.Quit(false);
                Marshal.ReleaseComObject(application);
            }
        }
        finally
        {
            impersonation.CloseImpersonation();
        }
  }

首先，我做模拟使用受信任的域用户帐户的字交互（ImpersonationManager是自定义组件）。该用户有权限打开\保存\关闭Word应用程序。在我的测试，这是我自己的帐户：）

Firstly, I make impersonation to use trusted domain user account for word interaction (ImpersonationManager is a custom component). This user has rights to open\save\close Word Application. In my tests this is my own account :)

然后，我创建的Word应用程序实例。在模拟账户开始WINWORD过程。

Then I create Word application instance. WINWORD process is started under impersonated account.

不过，在调用打开方法后，它总是返回null。没有例外，在事件查看器中没有资料。

But after "Open" method is invoked it always returns null. No exceptions, no info in event viewer.

此外字进程加载在此之后（1核CPU）100％的CPU。

Moreover Word process loads the CPU on 100% after this (1 core of CPU).

如果我运行相同的code（不带模拟）作为控制台应用程序，它工作正常。

If I run the same code (without impersonation) as console application it works fine.

我不知道什么可能是这里的问题？

I wonder what can be the problem here?

更新它工作正常，如果Visual Studio开发服务器作为主机的网站

Update It works fine if Visual Studio Development server is used as host for the site
