If you receive the "Network is Not Connected. Update Cannot Proceed" error message when you try to install/launch the Navigation Updater program, it is not because you have no Internet connection. At this stage the program is experiencing issue with either downloading the update or copying the files to your local drive and somehow this process cannot be completed.
The underlining issue has to do with security which could be either local file/folder and/or network settings.
For example on Mac OS, enabling the folders setting should fix the issue.
For Windows OS, you can try to temporary disable the firewall, anti-virus, and anti-malware.
Please also check whether you meet the system requirements.
