Hello Karlo,

An antivirus software or firewall is blocking NodeXL from downloading the required files.

Solution 1: Add an exception for http://www.nodexlgraphgallery.org to your antivirus/firewall.

Solution 2: Try a different internet connection.

If you run into any other issue, please have a look at this page: https://www.smrfoundation.org/nodexl/installation/
