I am calling an excel application from my .aspx page. I am also manipulating the cells programitically. But I get the following error.

System.UnauthorizedAccessException: Access is denied. I am running the application on IIS5. I have tried including the "all permissions" for ASPNET account and IUSR_MachineName account, but am still getting the same error.


I am bnging my head. Pls help.
