Im using VS 2005 and MS office 2003

_Document oWordDoc = oWordApp.Documents.Open(ref fileName,
                                    ref missing, ref readOnly,
                                    ref missing, ref missing, ref missing,
                                    ref missing, ref missing, ref missing,
                                    ref missing, ref missing, ref isVisible,
                                    ref missing, ref missing, ref missing, ref missing);

Need urgent help to sort out
At this I'm getting error as :
Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
