我尝试添加一个 COM-Control。我采取的步骤：
1. 在工具箱中单击鼠标右键
2. 选择 COMComponents 选项卡，然后选择“Adobe PDF Reader”
3. 单击“确定”按钮
4. 现在尝试将 Adobe PDF Reader 控件拖放到用户控件中-> 失败错误：
"Failed to create component 'AxHost'. The error message follows: 'System.Runtime.InteropServices.COMException (0x80004005): A wrapper assembly is not registrated for this type library.

我现在能做什么？
提前感谢每个回答。
