3.常见问题积解决方案
问题1. 无法将为“Microsoft.Office.Interop.Word.ApplicationClass”的 COM 对象强制转换为接口类型“Microsoft.Office.Interop.Word._Application”。此操作失败的原因是对 IID 为“{00020970-0000-0000-C000-000000000046}”的接口的 COM 组件调用 QueryInterface 因以下错误而失败: 加载类型库/DLL 时出错。 (异常来自 HRESULT:0x80029C4A (TYPE_E_CANTLOADLIBRARY))。
解决方案1：
到以下目录新建2个文件夹，然后就正常了。
C:\Windows\SysWOW64\config\systemprofile\Desktop
C:\Windows\System32\config\systemprofile\Desktop
解决方案2：
1.如果解决方案1还没有解决我们的问题！请确认是否是32位的Office
，如果是卸载安装64位Office
其它
