主题：word模板异常

调用打印模板时出现如下提示：

.NET Framework 版本：4.0.30319.34209
Foxtable 版本：2020.1.19.19
错误所在事件：窗口,收款管理,Button7,Click
详细错误信息：
Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: 库没有注册。 (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).
是不是office 安装异常？请指教，谢谢！！
