Elements 12

Got a refurbed computer, which has Windows 10 Pro on it. I tried to install Elements 12 and it goes through the whole process. I have to got to the website it says to, get the code, and then it says "You're all set" yet nothing happens. When I double tap to get Elements open, the whole process starts again. I recall that every time I would install Elements 12 it was a hassle, but foolishly didn't record what I did to make it work. This is probably the 5th computer. I tried everything I could find online and asked ChatGPT. That last attempt, just now, was in safemode. Understand, it installs fine, but just won't let me actually get to the program. I am kicking myself for not buying Elements 24. I just kept spending money on bills and one Christmas and now here I am not able to use a product I own.
