I have a web application which is used to send email. In this application, I am reading data from an Excel file and send email.
This is working fine in the local system, but not working after uploading on the server.

Error E_ACCESSDENIED in C# Microsoft.Office.Interop.Excel()

I have created a windows service that repetitively updates the same excel file. While running the Windows Service, I am receiving the following Error:

You need to grant permission to 'Launch and Activate' for the user running IIS.
Start-->Run-->dcomcnfg
Under Component Services\Computers Right-Click 'My Computer'
Permissions are under COM Security
