Interop.Excel.dll 11.0 throwing exception on Machine having only Excl 2003

I have delevloped an applicatin in C# using Microsoft.Office.Interop.Excel.dll 11.0 . When tested on systems having Excel 2007 and Excel 2003 or only Excel 2007 it works fine but when tested on systems having only Excel 2003 , though the ApplicationCalss object is created but some of its properties throws runtime exception for example

'oExcel.Chart threw an exception of type'
System.Runtime.InteropServices.COMException (0x800A03EC):

'oExcel.Column threw an exception of type' System.Runtime.InteropServices.COMException (0x800A03EC):

While there are many other properties which are set without exceptions

Due to which while opening Excel file through aplication is also throein errror

Please help to find out why COM component for Excel is throwing exception on machine having Excel 2003
