Folks, yet another stumble with SSIS and Excel. This time I am using Microsoft Office 11.0 Object Library. The code runs fine on Windows Server 2003.

Below is the code sample.


using Microsoft.Office.Interop.Excel;

using Excel = Microsoft.Office.Interop.Excel;

using System.Runtime.InteropServices;

Excel.Application m_ExcelApplication = new Excel.Application();

m_ExcelApplication.Visible = false;

m_ExcelApplication.UserControl = false;

m_ExcelApplication.Application.ScreenUpdating = false;

m_ExcelApplication.DisplayAlerts = false;

string strFileName = @"d:\testing\testing.xls";

Excel.Workbook m_ExcelWorkBook = m_ExcelApplication.Workbooks.Open(strFileName, //FileName

2, //UpdateLinks

bReadOnly, //ReadOnly

Type.Missing, //Format

Type.Missing, //Password

Type.Missing, //WriteResPassword

true, //IgnoreReadOnlyRecommended

Type.Missing, //Origin

Type.Missing, //Delimiter

false, //Editable

Type.Missing, //Notify

Type.Missing, //Converter

Type.Missing, //AddToMru

Type.Missing, //Local

Type.Missing //CurruptLoad



When executing the Open function. I received the following exception:

Microsoft Office Excel cannot access the file 'd:\testing\testing.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.

However, when I removed the directory information and just give it the file name: 'testing.xls' - I put testing.xls in to the same directory as the Windows Service- everything works fine, bizarre isn't it.

Research shows that automation is an issue with Windows Server 2008, specifically the 64-bit version. The 32bit version works, as well as windows 2003 32/64bit. I'm unsure at this point as to whether it affects only SERVICES or APPLICATION automation as well.

I dug in further and figured out the solution which is pretty crazy and actually motivated me to blog this for thousands of you who may run into this hair-pulling problem with SSIS and Excel.


For Windows 2008 Server x64: Create the following directory:


For Windows 2008 Server x86: Create the following directory:


Thats It!! Voila!! You are all set to go…..

  •'t work for me.  I am on Win 2008 R2 64 bit but running on a Virtual Server don't know if that has anything to do with it or not.

  • Are you sure you created: C:\Windows\SysWOW64\config\systemprofile\Desktop ?

  • The solution solved my issue with Excel.  Thanks so much!

  • YES!!!! this solves my problem. thank you so much

  • Hi

    Now mine at least runs... but runs and runs as if hanging.  Can you tell why?


  • Hi Marlene,

    Is the hang scenario from a SQL Server job? Can you run the package successfully from command prompt or BIDS?


  • Thanks a million, this fixed it for me.  Luckily I still have some hair left.

  • This solution worked for us!  What an obscure problem/solution!

  • It worked for me !! Thanks a Ton. I have no clue how its related but it does work

  • Many Thanks... It solves my problem!!!

  • Dude!  You have saved me hundreds of hours of thinking it was my code or permissions...  I owe you a beer!

  • Hey Eric!

    Seriously? Tell me where are you located. I can go anywhere for a beer :P


  • Thank you, it worked for me as well.

  • Thank you -- I was pulling my hair out trying to tie a piece of excel automation into a Team City Build project (don't ask, its a long story).

    Anyhow, creating the directories has fixed a problem I was just about ready to give up on!

  • This worked for me. As a previous commenter said, so obscure! Thank you.
