The download is not indicated in the purchase receipt, because there's no need to, since the installer is freely available at any time before purchase, and there's no additional download after purchasing, that's why there's no download link indicated on the purchase receipt.
The one and only installer it's the Trial, and the link is on the product's page, and it's repeated on the main "Products" pages, I've just checked all the links and they all works fine so, it's your browser that is likely showing you an oudated cached version of our site.
