Vista ASP.NET 2.0 Cannot open Excel File using Microsoft.Excel 12.0 COM object


New Member
I am using an ASP.NET 2.0 web application using the Interop assembly pointing to the Microsoft.Excel 12.0 COM to open and write to a spreadsheet.

I have set the permissions for the DCOM to allow NETWORK SERVICE to open the Excel application, but when I try to open the actual file I get Exception from HRESULT: 0x800A03EC.

I have changed the website directory permissions to allow NETWORK SERVICE full access to the folder and I still cannot open the file.
