Download Premiere Elements 2020 ????

As @John T Smith mentioned Adobe provides download for only the latest two versions of the software so 2020 is not available for download. For 2020 Adobe has no publicly available download links, you will have to contact support and ask for the download link, they may provide one. Please be careful if someone contacts you regarding providing the links, it most probably will be malware laced. To contact support, login to your account and navigate to the URL below.

Direct Download Links https://prodesigntools.com/tag/ddl MAY help
-you MUST do what it says in Note: Very Important Instructions
-https://prodesigntools.com/adobe-cc-2015-direct-download-links.html#download-instructions
-the prodesign links go directly to Adobe's file server, so this process will
--only work until Adobe completely removes the old version(s) from the server
.
IF/When you do have a download, be sure to copy it to AT LEAST one external device
-since Adobe does sometimes remove old versions from the server
-a usb flash drive or external hard drive, or write to a DVD
-plus a text file containing your serial number if you have a serial number program

If you do not already have a serial number from a previous purchase there is no way to obtain version 2020
