Firefox doesn't work for me either. I didn't bother with Edge since it's now based on Chromium.
I poked around a little bit more on SolidWorks' website, using Internet Explorer. If you go to my.solidworks.com/support, then click on the "Desktop Solutions" tab, there's a link for Downloads. Clicking that takes you to solidworks.com/sw/support/downloads.htm. In the middle of that page, where the actual downloads should be, is a link that says, "Login for full access to the latest SolidWorks release and updates" (I'M ALREADY LOGGED IN!!!). Clicking that link does nothing but reload the same page (at least in Explorer; in Chrome and Firefox the link was dead, and did nothing at all).
Then I tried registering as a student on the
My Profile page. I entered "Experimental Aircraft Association" as the school name, "2021" for year of graduation, and "https://eaa.org/" for the school's website. It accepted the EAA serial number and said I now had a Student account. Still no download link.
I fooled around for a few more minutes (still using Explorer), trying various things, and ended up back on the My Profile page. Lo and behold, a download button had appeared!! I picked "2020" from the dropdown, punched the Download button, and it
FINALLY fed me SolidWorksSetup.exe.
Out of curiosity, I went back to the My Profile page with Chrome, and the Download button now appears in that browser as well.
I've been using computers since the late 70s and I've seen a lot of bad user interface and website design, but this takes the cake. What an unbelievable goat rope. Dassault Systemes should be ashamed.
Wish me luck with the installation...
