PSE 2020 disk not installing on Windows 23H2

My HP TE01-1022 (specs fine for PSE) was originally running Photoshp Elements 18 (2020). PSE was installed via disk with activation code when the PC was new, about 3 years ago. PSE ran without any problems. Recently, there was a storm, and the PC crashed. The PC was repaired with a new motherboard (same as original). The PC is now running latest Windows 11 23H2, the most recent Edge and Firefox, updated dirivers, updated apps.

Just about all apps were easily re-installed; some from disks, others from internet downloads, with all working fine. However, when I go to reinstall PSE via the disk, I get the drop down alert from Adobe stating that I should "Update your browser," and could go no further with the installation. As far as I can tell, as everything is fully updated, why this alert?  I have read and re-read this Adobe link (https://helpx.adobe.com/x-productkb/global/update-operating-system-and-browser.html), but unfortunately, I'm still at a loss as how to get PSE 2020 onto my computer. and would most appreciate some specific guidance. Thanks.
