I've replied to you via email as well: as with all our products, you can download the installer even before purchasing, because we sell it in a Trial version that can be unlocked with your Serial Number so, that's the only installer we have.
You should see links on the main Products page. If you don't see the Hawaii links, it might be your browser is caching the page and hasn't realized the web page has been updated so, it still showing you the old page.
In this case, Refreshing the page (F5 on most browsers) should fix the problem.
