Install or upgrade? You have the option of a fresh install or to upgrade from an existing version.

Select install for a fresh installation Click Next
At this point you are prompt to select a security level (firewall preset rules), if you already have experience and know what you are doing, you can set the security on this screen. I do not recommend setting a high security here because you may not be able to troubleshoot later in case you are having problems connecting to the Internet etc.
Leave the security level as Standard Click Next
