Failed with Workbooks.Open RRS feed

  • Question

  • User-144431078 posted

    Does anyoneknow why IIS7 can´t open Excel or Word Applications with ASP?

    Set xl=CreateObject("Excel.Application") is not giving Error, but Set wb=xl.Workbooks.Open("File.xls") yes.

    This code works O.K. with IIS6.

    The error descriptions talks about Resources, but where are those resources?

    Look at event logs, there should be DCOM related error thrown up / may be event id 10016.

    This is most probably related to local launch and activation permissions for IUSR and Excel.

     i have exactly the same problem (IIS 7,5, windows server 2008 RC2). I dont see excel (or the corresponding clsid) under component services, so i dont understand how i can modify the needed rights. I believe under Windows 7 and Windows server 2008, it does not work the same way as under XP

    Here the solution (same solution in link entry posted previously):


    I found the solution. I have to give dcom rights to excel(office). Here is what to do on windows 7 and windows server 2008:

    1. go to DCOMCNFG (component services)
    2. In the left tree structure, right click on My Computer and select Properties
    3. Click on COM SECURITY tab
    4. Give Permissions to Network Service and Users in the "Access Permissions" and "Launch and Activation Permissions" by clicking the Edit Default buttons.

    Hi @ knoepdan1,

    Glad that you got it worked out.

    I have a suggestion. Since this is old and did not help you.

    Since you have an updated solution maybe create new thread put in the topic "Solved" and your information.

    Then the next time it will save a user some time.

    Just a thought.

    The solution for Windows Server 2008 posted above did not work properly :-( 

    Having given the rights to the NetworkService account (and the account of the application pool) i could create excel reports in the asp.net application via Excel. Unfortunately, today, it no longer works and the same error occurs. I checked the rights and they are the way they should be.

    There must be another setting affecting the outcome :-(

    Hi @ knoepdan1,

    Since the OP Thread had an answer and it does not work for your

    case then the best choice would be start a new thread

    and information for your system and information from IIS Server logs.

    Then users can help your special situation.
