Question

Hi,

I have installed interop assembly on server but receiving following exception after hosting inside IIS -

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

I have tried on both Windows Server 2012 & Windows Server 2008 R2.


I have tried to provide access to IIS user, network service user as well as everyone inside component services - DCom Config - Microsoft Word 97 - 2003 Properties but nothing worked till now.

Any solution would be great help to resolve this issue.



Thanks

Hello Saurabh,

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side. If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution. Read more about that in the Considerations for server-side Automation of Office article.

As a workaround you may consider using the Open XML SDK, see Welcome to the Open XML SDK 2.5 for Office. Or just any third-party components designed for the server side execution.
