The system and method allows a casino operator to re-configure one or more electronic gaming machines as part of a multicast. Where any reconfiguration requires a software package A and any dependent package B, a server is configured to combine as part of the multicast both packages A and B. The system and method also provides for scheduling reconfiguration though multi-casting. In the event any data packages are lost, corrupted or not received, those packages are repackaged and the data packets are re-sent as a multicast.
