Trouble installing Elements 2018 on Mac

[drizzo28]

I am trying to download Elements 2018 on my Mac (has High Sierra operating system).  It downloads, but when I open the installer it says Elements 14, and my serial number will not work.  Error message that the serial number doesn't match the product.  I am sure that the download is 2018 - it says this as it is downloading.  What to do???

Thanks.
