Okay, being an Alpha backer I get the newest toys to play with. So, I wasn't aware of the fact that there was a version that was less fleshed out than the now labeled Legacy Horizons, since on my launcher I could only choose between 4 options before this update; being:
Elite Dangerous Odyssey
Elite Dangerous Horizons
Elite Dangerous Arena
and
Single Player Combat Training
So I could not even play with Elite Dangerous without horizons up until now. To me it looked like Fdev saw fit to add a new one to the mix now that I didn't know about, hence the question.
As I am gravitating towards legacy more than the new stuff which IMHO has lost its atmospherics charms I will be trying out both Legacies versions.
Thank you all for the responses, it makes sense now.
P.S. Yes 32 Bit was dropped quite a few years ago when windows 10 becam the platform of choice and windows 7 was ditched, and also there it was not possible to land on planets.
