Fresh install of 4.5.1 and site pages are all error 404

[The Guy]

As the title says, the index.php shows the forum list all intact and amdin pages work just fine. However when I click on a diffferent page, even if its a forum, all the pages show up as Status Code 404 page not found?

It looks like you have turned on FURLs in ACP but have not uploaded .htaccess yet.
