A quick warning to people:
The user registration button will not work if Internet Explorer is not your default browser. The button on the CD autorun screen will only open a blank page if Firefox is your default browser like mine was.
Just open IE go to tools > Internet Options > Programs > and then tick the option at the bottom for Internet Explorer to check if it is default when it's opened. Then when you click on the User Registration button, select IE as default and you're away.
