Once you've registered an account on the ServerGuard website and have successfully completed the checkout process, you can now download your copy of ServerGuard. To do this, make sure you have logged in with the details that you've used to register (quite obviously), and click the Downloads navigation button located in the top right area of the website. In that area of the website, you will see the current release version of ServerGuard and a link to download it. Simply click on the link and you will be forwarded to a page where your download will start automatically.
Since we do update ServerGuard from time to time, you're going to have to visit the website to grab the latest version for use on your servers. We highly recommend that you update as soon as possible because the latest versions may include new features, enhancements, critical bug fixes, etc. When you visit the downloads section and you haven't updated to the latest version of ServerGuard, the website will display a notice for you prompting you to update to the latest version.
