Windows Service 中访问Excel对象时拒绝访问

环境：Win2008R2， Excel2010

c# 写的Windows service，本地直接跑，一切正常，发布安装后，log中提示

System.Runtime.InteropServices.COMException (0x800A03EC): Microsoft Excel cannot access the file .
There are several possible reasons:
• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.

解决方法：

1. 任务管理器中关闭所有Excel进程
2. 打开组件服务，cmd中敲dcomcnfg
3. 依次展开 控制台根节点--组件服务--计算机--我的电脑--DCOM配置，找到Microsoft Excel Application
4. 右键属性-标示 选择运行此应用程序的帐户中选中“交互式用户”，确定

有人说建文件夹即可，不过我的环境下试了没用

・Windows 2008 Server x64
C:\Windows\SysWOW64\config\systemprofile\Desktop

・Windows 2008 Server x86
C:\Windows\System32\config\systemprofile\Desktop
