Upon launching the tool it will immediately take you to the Crestron address book utility where you will either reference the address entry for the processor you are wanting to update or you can create a new entry entering in the IP address of the processor on the local area network.

After about 10-15 minutes your MC3 processor should have updated and given you a status update on whether it was completed and if there were any failures. Also to note that it is always a good idea to hard wire your computer to the network to avoid any issues with your wireless connection. Good luck with the updates.
