Thanks for your direct message Tanis, but as said, I prefer to respond in public on the forums, so I came here to give your post a "push". I have occasionally installed Moodle on Windows 7 local host and this has occasionally happened to me - the blank screen on this page. I don't know why but if I change the address in the URL to the front page of my Moodle or to another one such as /course/index.php it does sometimes work. So try that first. If you are getting everything blank, then post back and hopefully someone with more understanding of installing Moodle will be able to advise.
