MATLAB: Trial installation is asking for an activation key

muddled installation

I am trying my best to acquire a trial installation so I can see if I want to become a licensed user. I finally got the download working and the actual installation appears to be starting, but now it is asking me for an activation key. I don't have one and I don't know where to get one. That screen is also showong me three licenses: 7126082, 7126043, and 7126020. What the heck am I supposed to do with that?
What do I have to do to complete the installation so I can try this thing out?
I suspect the three licenses may be because I started the download a couple of times, but ran into problems and abandoned it.
Mathworks seems to keep putting up roadblocks to my getting a trial version. I've installed dozens of programs over the years. I have never encountered a process so convoluted and riddled with pitfalls. I have spent several hours over several days just trying to get this to work. This whole install process is a muddled mess. If MatLab didn't have such good reviews, I would have given up and go to something else.

I guess there won't be any more discussion here, so I'll submit this "answer" so I can close it. It seems like there ought to be a way to just close a thread even if there are no answers so we don't have to sumbit faux answers like this one.
