If the Pairing Wizard software displays an error message, perform the following steps:

• If you get a Network refused error, make sure you're using a 802.11b/g network and that there is no mac address filter on your router.
• If you get a Device busy error or if the Continue button is grayed out during the installation, try using another USB to mini USB cable. You can also try connecting the cable to another computer.  
• If you see the message “several Withings devices are connected to your computer", unplug all other USB devices connected to your computer. You can also try connecting the cable to another computer.  

Important: Please make sure that you are using the most recent version of the Pairing Wizard. To do so, follow the instructions here to access the Pairing Wizard download.
