Diablo 2 Problems installing, doesn't even start

So I bought and downloaded diablo 2 and lord of destruction. When I start it up to install it, it just automatically goes to Play Diablo 2 and nothing happens. No cd key request or anything.

I got rid of any other versions I had before, so I have no clue.

I Have a long list of things I tried on my post straight up like 12 hours of research and it still doesn’t launch. However these workarounds do work for some people.

also svens 3rd party software which also didnt work

did you manage to figure this out or have you been able to reach someone from blizzard? i cant seem to figure this out either,
