In order to give ASP.NET the permissions it needs to use Excel, you'll likely need to add the line <identity impersonate="true"/> to your web.config file or configure your app to run under an appropriate user account.
 
Access denied error while using excel object

any body suggest me the solution for this

I am using excel object in my server side code. But, I am
getting Access denied error for the user asp.net . I gave
full permission for the Asp.net account on the directory
where I am running the application.Do I need to change any
security permission for excel?? Here is my code and the
exception that I am getting.

Excel.Application excel= new Excel.Application();
int rowIndex=1;
int colIndex=0;

PLz help me

To grant ASP.NET write access to a file, right-click the
file in Explorer, choose "Properties" and select the
Security tab. Click "Add" to add the "{machinename}
\ASPNET" user. Highlight the ASP.NET account, and check
the Write box in the Allow column.
