connectivity issue with SapBobscom90.dll to lower version of SAP Business One

Hi,

while connecting from SApBobscom90.dll to sap business one 8.82, i got a issue "Retrieving the COM class factory for component with CLSID " . is it possible to connect sapbobscom90.dll to sap business one lower version or is there any backward compatibility. Could you please help me on this? Thanks in advance..
