Error ‘Microsoft Office Excel cannot access the file’ while accessing Microsoft Office 11.0 Object Library from SSIS

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:

β€’ The file name or path does not exist

β€’ The file is being used by another program.

β€’ 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…..

    Uh…no…doesn'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.

  2. Debarchan says:

    Are you sure you created: C:WindowsSysWOW64configsystemprofileDesktop ?

  3. Alice says:

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

  4. Terry says:

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

  5. Marlene says:


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


    1. Deepika K says:

      Hi, how did you resolve your issue ? I’m facing thew same problem.

  6. DebarchanS says:

    Hi Marlene,

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


  7. Mike says:

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

  8. Brandon says:

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

  9. Ankit says:

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

  10. says:

    Many Thanks… It solves my problem!!!

  11. Eric Fisher says:

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

  12. Hey Eric!

    Seriously? Tell me where are you located. I can go anywhere for a beer πŸ˜›


  13. Gliese 581 g says:

    Thank you, it worked for me as well.

  14. James Field says:

    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!

  15. Lisa says:

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

  16. Jim Burfield says:

    Worked for me too – in my case for Windows 7 32-bit / Excel 2010.

    I just created C:WindowsSystem32configsystemprofileDesktop (I was only missing the Desktop folder), and that was the solution for nearly a full day's worth of hair pulling.

    Thanks so much!

  17. FG says:

    Thanks a ton for this solution! This is one for the textbooks. I had a powershell script that ran fine when executed manually but didn't work when run under task scheduler. I installed a new scheduler (nncron) and nothing changed. But the logging now gave a clue as to why the job was failing. The open call to Excel was failing. Made your change and the darn thing started working correctly. Wow. I hate Windows more than ever now, but thank the gods of everything holy there are folks like you around to battle against the evil empire in Redmond.

  18. Andrey says:

    your post helped me second time!

    i had this issue about year ago and successfully forgot solution…


  19. Amar says:

    Wow — I tried the above solution and it worked like charm πŸ™‚ We were fighting on this issue for almost 4 days and tried many stuff .

  20. Anand kumar singh says:

    i have created the folder but it didn't work for me

  21. Jeshur says:

    It worked for me! Thanks a ton!

    But now I am facing the same issue for Windows Server 2012 and the said fix ain't fixing it! Any other solution for WS 2012?

  22. j says:

    Voila nothing. I was able to correct it on a development machine using dcomcnfg.exe and dcomcnfg.exe /32 because of the inconsistancy of com apps and 32 office on a 64 bit machine. BUT I duplicated all the settings on another cloned machine and NOTHING – I'm MS certified and started my days in COM but this is terrible. Why is Excel still a COM object and not part of C#,Framework and safe….code.

  23. Arno Schoof, InsightCS says:

    Brilliant, I had the same problem and would never have found this solution myself…!  It works for me in Windows 2008 server reading Excel files through a Windows server.

  24. sunny says:

    Worked for me…nice post. Thanks for this.

  25. Vikas says:

    It works for me…really woth writing this one but needs more tagging here.

  26. Gomti says:

    This isn't a workable solution, what if I have to write to file on a network?

  27. M akins says:

    Wow. Thanks a lot! Saved me prob hours of garbage research.

  28. tej says:

    Now mine at least runs… but runs and runs as if hanging.  the job which is calling the conversion block is in running stateeven after convesion completes and put a lock on xlxs file.

  38. Norbert says:

    It worked for me, thanks a lot, but… Can anyone explain me, why this is working?

  39. Pulkit K says:

    Awesome! This worked for me too! My problem was: I was able unable to open a workbook via a vbs script scheduled in the Task Scheduler to run even when the user is logged out. I've been trying to resolve this for a week now. Just created the Desktop folder and it worked flawlessly! Thanks! πŸ˜€

    Is it too late to ask how did you ever come across this solution?

  40. Suraj says:

    Thanks for posting this.. was breaking my head over why it works from cmd but not when run as a service..  πŸ™‚

  41. Prathap says:

    Create the folders as well as provide write access to the App pool account that is running web application.  After performing this,I was able to run on windows 7 machine but application is hanging on windows Server 2008 R2 and Office 2007 Excel

  42. Ole Hem says:

    Works also on Server 2012 through an Dynamics AX Aos service.

    The solution is really crazy!!!!!!!!!!!

  48. Martas says:

    Hey! It works! It saved mlds of hours for me. Once you're in Czech, just give me a call for a beer. I pay! πŸ™‚

    THX once again.

    …..damn illogical obstructions…

  49. Nikolay Galibov says:

    This solution is also suitable for IIS 7.5?

  50. Brijesh Kothari says:

    Thanks a lot to you. You have helped me solve my issue.

  51. Sujoy says:

    Such a funny solution!Thanks a lot Deb!

  52. KJMClark says:

    A few other notes: Remember that the user account the service is running under will need to have appropriate permissions on those desktop folders.  It doesn't do any good to just create the folders if the account that will try to access them has insufficient permissions there.  If you can't even get your COM interop to start, you may need to go into dcomcnfg to give launch permission to that account as well.  Remember to run dcomcnfg as administrator, expand "Console Root"/"Component Services"/"Computers"/"My Computer".  Right-click "My Computer" and find the "COM Security" tab.  On there, choose "Edit Default" under "Launch and activation permissions".  Make sure your account is listed there, and give it at least "Launch Local" permission.  This new security model is such a pain.

    Life saver.

  65. Barun says:

    It saved me few hours… Thanks!!!

    In my case, it is a normal executable file, put into windows task scheduler. The executable run OK if it run from windows explorer, but while executing from task scheduler, it logs the bizarre error message. I tried this solution and it worked.

    Thanks again.

  66. Reino Boonstra says:
