Making an Excel File

Hello,

I have a web site that is accessing the Excel Reference:

Dim Excel As New Excel.Application
When this line of code is executed I get the following error.

ASP.NET is not authorized to access the requested resource. Consider
granting access rights to the resource to the ASP.NET request identity.
ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or
Network Service on IIS 6) that is used if the application is not
impersonating. If the application is impersonating via <identity
impersonate="true"/>, the identity will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated request user. 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
appropriate user or group. Highlight the ASP.NET account, and check the
boxes for the desired access.

I have attempted what is suggested with no success.

Any Suggestions will be greatly appreciated. All I am doing is making an
Excel File out of a dataset.

I don't recommend COM interop with Excel from ASP.NET, but if you're
determined to make it work, the details are here along with some better
options:
