The install manager is a small program that first need to download and install like any other installer file. You can download it by clicking on the button/link at the top of your download page (the link from your email confirmation). From your description, it doesn't seem like you've done that. When it's been installed, run it and you can paste in your download URL into the actual program. You will see all the files in your order there, and there is a "Download and install" button.
