Question

我正在使用vb.net创建word文档，我有这段代码：

Imports word = Microsoft.Office.Interop.Word
Imports xl = Microsoft.Office.Interop.Excel

Dim oWord As New word.Application
Dim oDoc As word.Document
oWord.Visible = global_variables.ShowWordDocs

但是在运行时，我在最后一行收到此错误：

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: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

最后一行的值等于False

我已经尝试修复Microsoft Office - 我已经安装的是word，excel，office共享功能和办公工具 - 2010版

错误意味着COM接口存在问题。您是否尝试重新注册（RegSvr32.exe / i ...）用于Word / Excel的COM DLL / TLB / OLB？这些将位于Office安装文件夹中（例如C：\ Program Files \ Microsoft Office \ Office14）
