It seems your antivirus/firewall is blocking the download of a file required by the new version to support the new LFNC airport, which is done as soon as the program starts ( normally, when the antivirus/firewall is not interfering )
If you download the Universal Installer again, which has been updated too, should fix the error, since the file is contained in the installer, so it won't matter if the antivirus/firewall is trying to prevent the updater from downloading it.
