Generering af Excel virker ikke på windows 2003-server

Hej
Nedenstående kode virker fint lokalt på min maskine, men ikke på webserveren, Windows 2003 -server.

Efter at have googlet mig frem kunne jeg se at der ikke var anden vej udenom end at spille en licens på at

installere office-pakken på serveren. Efter dette var gjort fik jeg fejlen:
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to

the following error: 80070005

Jeg gave efterfølgende rettigheder, som beskrevet i dette link:

Efterfølgende sker der nu nada, når jeg trykker på LinkButtonExcel-knappen.

Nogle forslag?



Kode:

using Excel = Microsoft.Office.Interop.Excel;

      int i = 2;
      foreach (DataRow theRow in dataset.Tables[0].Rows)
      {
          DateTime dt = Convert.ToDateTime(theRow["Date"]);

          xlWorkSheet.Cells[i, 1] = theRow["Date"];// dt.ToString("yyyy/MM/dd").ToString();

          xlWorkSheet.Cells[i, 11] = theRow["Returnr."];

          i++;
      }
      // Autofit the columns
      xlWorkSheet.Columns.AutoFit();
