Retrieving the COM class factory for component fai

Question

I am using an excel object (COM component) for excel manipulation. It works fine on my PC, but when I deploy the application to our Intranet I am getting this error:

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005

I am using windows authentication and impersonate=true in my web.config.

I made all the settings in component service but it still gives the same error.

Please help

Answer 1

The CLSID you describe is for the Microsoft.Office.Interop.Excel.ApplicationClass. This class basically launches excel.exe through InprocServer32. If you don't have it installed then it will return the error message you received above.

Answer 2

I have Done the Following Things in IIS 8.5 (Windows Server 2012 R2)Server and its Worked in My Case Without Restart:

1. Selecting The Application Pool That Connected to The Application in IIS
   

2. And Right Click --> Advanced Settings --> Process Model --> Select Local System Instead of Recommended ApplicationPoolIdentity
   

3. And Make Sure C:\Windows\SysWOW64\config\systemprofile\desktop Have Enough Access For Users.
   

4. Refresh the Website Link that Connected With this Pool

Answer 3

You will also get this error when there are stale EXCEL.EXE processes in the system (Use Task Manager --> Processes tab to view these.)

Kill all those instances and the application would work normally.

In case it helps somebody:

I am running Windows 7 64-bit and I wanted to register a 32-bit dll.

First I tried: regsvr32 and got the following error:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {A1D59B81-C868-4F66-B58F-AC94A4A7982E} failed due to the following error: 80040154.

Then I tried to add the application through the Component Services (Run->DCCOMCNFG) (http://www.justskins.com/forums/difference-registering-dll-using-regsvr32-and-component-services-17280.html) and got the following error:

System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {A1D59B81-C868-4F66-B58F-AC94A4A7982E} failed due to the following error: 80070005.

There are many links to solving it but what worked for me was: Console Root -> Component Services -> Computers -> My Computer -> COM+ Applications -> your_application_name -> Properties: Security tab: Authorization: Uncheck 'Enforce access checks for this application'.

I don't know what it does.

I can understand your pain. In my case the error got resolved by performing below steps:

1. Start > Run > dcomcnfg.
2. Open the folder DCOM Config and Select Component Services > Computers > My Computer > DCOM Config.
3. Select “Microsoft Office Word 97 – 2003 document”/”Microsoft Excel Application” and go to its properties.
4. In "Security" tab set “Launch and Activation Permissions” need to be Customize (Authorized user).
5. Now go to IIS and select application pool of the Web and go to its Advanced Settings and select “NETWORK SERVICE” as identity user.

Hope this helps.

There's one more issue you might need to address if you are using the Windows 2008 Server with IIS7. The server might report the following error:

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.
