I am trying to make a dynamic charting function with c# and asp.net but keep getting the following error message;

(COM object with CLSID {0002E546-0000-0000-C000-000000000046} is either not valid or not registered. )

OleDbDataAdapter da = new OleDbDataAdapter(sqlStr, oleDbConnection1);
da.Fill(ds);
OWC10.ChartSpaceClass oChartSpace = new OWC10.ChartSpaceClass();
System.IO.StringWriter sw = new System.IO.StringWriter();
 XmlDocument xDoc = new XmlDocument();



I have added all the supplied dll files but am not sure what is wrong. I would appreciate some help, thanks!
