vb.net word應用程序互操作對象錯誤

Question

我正在使用vb.net創建Word文檔，我有以下代碼：

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

但是在運行時，我在最后一行收到此錯誤：

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)).

最后一行的值等於False

我已嘗試修復Microsoft Office-我已安裝的所有軟件都是Word，Excel，Office共享功能和Office工具-2010版

Answer 1

錯誤表明COM接口存在問題。 您是否嘗試過重新注冊（RegSvr32.exe / i ...）Word / Excel的COM DLL / TLB / OLB？ 這些將位於您的Office安裝文件夾中（例如C：\\ Program Files \\ Microsoft Office \\ Office14）
