Running Excel in an ASP.NET web application

Running Excel in an ASP.NET web application

I hope someone has an answer to this. I've created an web app that creates an Excel file. I got this error:

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

Another forum said that the problem was due to:
The problem is that by default Microsoft Excel as a COM object can only activated by the following accounts:


And it instructed me to edit the Component Services for "Microsoft Excel Application". I changed the security settings for "Launch and Activation Permissions" and "Access Permissions" to allow NETWORK SERVICE to do Local Launch and Local Activation.

I then changed my DefaultAppPool application pool to run as NETWORK SERVICE.

I refreshed my IIS

but the problem still persists.

My platform: Windows 7 Professional, IIS version 6.1, .net framework 4.0, //localhost website.

Thanks in advance for your help,

Jerry Scannell
