在c#调用word中的有关问题?

在c#调用word中的问题??
在网上找到别人的调用word的原码，但是我刚着网上的做法做了！也添加了word object libabry 11.0还是报错。
错误如下：Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80040154.

以下是原码：
  private void button1_Click(object sender, EventArgs e)
  {
  Word.ApplicationClass wd = new Word.ApplicationClass();
  object oMissing = System.Reflection.Missing.Value;
  wd.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing);

  Word.Document doc = wd.ActiveDocument;
  wd.Visible = false;

  object extend = null;
  object unit = null;
  object count = 0;
  object character;
  extend = Word.WdMovementType.wdExtend;
  unit = Word.WdUnits.wdCell;

  wd.Selection.Move(ref unit, ref count);
  wd.Selection.TypeText("会议通知");
  //换行 
  wd.Selection.MoveRight(ref unit, ref count, ref extend);

  count = 2;
  character = Word.WdUnits.wdCharacter;
  wd.Selection.Move(ref character, ref count);
  wd.Selection.TypeText("eeeeeee");  
  }

C# code

  private void button1_Click(object sender, EventArgs e)         {             Word.ApplicationClass wd = new Word.ApplicationClass();             object oMissing = System.Reflection.Missing.Value;             wd.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing);             Word.Document doc = wd.ActiveDocument;             wd.Visible = false;             object extend = null;             object unit = null;             object count = 0;             object character;             extend = Word.WdMovementType.wdExtend;             unit = Word.WdUnits.wdCell;             wd.Selection.Move(ref unit, ref count);             wd.Selection.TypeText("会议通知");             //换行             wd.Selection.MoveRight(ref unit, ref count, ref extend);             count = 2;             character = Word.WdUnits.wdCharacter;             wd.Selection.Move(ref character, ref count);             wd.Selection.TypeText("eeeeeee");                                }

OLE错误码0X80040154:Class not registered  
coclass Application 的 uuid(000209FF-0000-0000-C000-000000000046)

可能word的注册键出了问题，建议重装word

检索 COM 类工厂中 CLSID 为 {000209FF-0000-0000-C000-000000000046} 的组件时失败，原因是出现以下错误: 8000401a 。

运行dcomcnfg打开组件服务,

依次展开"组件服务"->"计算机"->"我的电脑"->"DCOM配置"

找到"Microsoft Excel应用程序"或"Microsoft Word应用程序",

右键打开属性对话框,点击"标识"选项卡,

点"下列用户",把管理员的用户密码正确填写进去...

点击"安全"选项卡,

依次把"启动和激活权限","访问权限","配置权限",都选择为自定义,
