What is going on with Adobe?

Well, it´s quite obviously, I´m just feeling VERY mad about Adobe and their strange behaviour!!!

I got an ORIGINAL version of Photoshop Elements 2020. With ORIGINAL package, ORIGINAL discs, ORIGINAL serial numbers.... as a matter of fact I had to re-install my computer completely new. After installing Windows 10 and all related updates I looked forward to get my Photoshop Elements running. Surprise.... the installer module tells me, my windows version is not supported.... correction, not supported ANY MORE!!! Who can that happen? The NEWSET version of my OS is not supported ANY MORE? So I tried to find some help here online. Well... I found out I somehow have to use Internet Explorer.... which has benn integrated in Edge in the meantime... very helpful to tell me it shouldn´t work in legacy mode or document mode.... what modes? Where can I find out what this means? How can I change it? So I kept on looking for other solutions. It was recommended to edit my registry.... really? Come on guys, I can´t even find out what Internet Explorers Legacy Mode is, do you really want me to edit the registry???

Next possible solution, find the download file for PSE 2020. Surprise, you can only find links for 2021 and 2022... so I looked up my Adobe account. This stupid web page asked me to enter serial number of PSE 2020. So I did... but guess what.... not the correct format.... it should be a 24-digit alphanumeric code. Yes, it is... I tried with dashes and withoiut dashes, no, it doesn´t work. After two hours nervewrecking search for support I tried something REALLY stupid: I clicked on "Contact".... well.... I clicked on "Contact"... again.... and again.... and again..... but nothing happened. So I tried from another computer, no big surprise, it didn´t help as well.

So, who ever may read this.... doesn´t it feel strange that you can´t find any support for a 2-year old software and the latest version of OS? And all the ways to help yourself lead to nowhere? And when you want to ask for help, it doesn´t work? Really, I´m most disappointed, always was under the impression Adobe could be better than that, but this really is the worst product support I´ve ever seen. Thanks for nothing.
