The EOS Utility network settings are now complete.
There is no need to complete pairing again if you continue using a
particular camera and computer together after pairing without
changing the settings.
When using this function the next time, simply turn on the camera
and start the pairing software. The connection between the camera
and computer will be established automatically.
You can add the pairing software to the software launched at startup
