首先應用中引入Microsoft.Office.Interop.Excel、Microsoft.Office.Interop.Word兩個dll，將嵌入式互操作類型設爲False，

對DCOM組件進行權限配置：
1、打開comexp.msc -32
2、Microsoft Excel Application、和Microsoft Word 97-2003 Document屬性裏面進行配置，如下：
標識：設爲“交互式用戶”
安全：啓動和激活權限添加“NETWORK SERVICE”，勾選本地啓動和本地激活，訪問權限添加類似
以上兩點設置完成後還有問題，繼續以下操作：
3、應用進程池標識轉換爲“LocalSystem”
4、在C:/Windows/System32/config/systemprofile和C:/Windows/SysWOW64/config/systemprofile目錄下創建名爲Desktop目錄
出現的問題：發佈到服務器上後，WORD轉換沒問題，EXCEL轉換PDF時轉換卡住，只能生成temp的臨時文件，以下操作解決問題：
4、在DCOM組件的Microsoft Excel Application、和Microsoft Word 97-2003 Document屬性安全中額外添加“IIS_IUSRS”用戶組，權限跟之前的“NETWORL SERVICE”一樣
