The download page text is not accurate. It suggests that after visiting the page where the user fills in their e-mail address, they will receive an e-mail with the serial number. That would be a one-step process.
What is not explained is that 1st e-mail instead has a link that must be clicked. It will take the user to a page that then states that the user will receive an e-mail with the serial number.
Now, when the user goes back to their e-mail they should find a second e-mail that has the serial number. This is a two-step process.
The 1st e-mail is a common “confirmation” link. Too bad the download page does not explain this two-step process to get the serial number.
