今天在一个客户这边出来一个windows service的问题。这个service需要启动excel程序,并且对一些excel文件做一些操作。

环境是:windows server 2008 x64+Excel 2007

总是报告错误:(类似下面这样)

Service cannot be started. System.Runtime.InteropServices.COMException (0x800A03EC): Microsoft Office Excel cannot access the file 'c:/temp/test.xls'. 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.

代码怎么看都是可以的,反复调试了service,问题最后解决了,大致有如下几点

 

第一步:在服务器添加有关的一个目录

这个方案参考了http://social.msdn.microsoft.com/Forums/en-US/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91?prof=required

This solution is ...

・Windows 2008 Server x64
  Please make this folder.

  C:/Windows/SysWOW64/config/systemprofile/Desktop

・Windows 2008 Server x86

  Please make this folder.

  C:/Windows/System32/config/systemprofile/Desktop

  ...instead of dcomcnfg.exe.

This operation took away office automation problems in my system.

A Desktop folder seems to be necessary in the systemprofile folder to open file by Excel.

It disappears from Windows2008, Windows2003 had the folder,
and I think it cause this error.

I think it is safer than "registry hack".

If you try this solution, please let me know results.

 

第二步:设置服务与桌面交互

第三步:关闭服务器的UAC(这一步至关重要,调试了一个下午,就是因为这个问题卡住)
