Right before installation, I got this pop-up window saying "The following error was detected while downloading update_installer_win64_1532732830.enc: Address family not supported by protocol family: connect Would you like to retry downloading update_installer_win64_1532732830.enc?"
Any solutions?

I see hints that this can happen if you have a misconfigured ipv6 configuration. That is, you might have incomplete ipv6 elements in your network configuration.
There is a Java option to get around this, but at the moment I do not know how to get Java on windows to pay attention to the option.
In the meantime you could go into your network adapter configuration and disable ipv6.

Could you go to command prompt and run "setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true" This worked for me
