Actually, I have tried to use the new 5.0 Game Manager on an old Windows 7 computer as well as on our Windows 11 computer, and it would not run on Windows 7 but instead gave me an error message.
If you are referring to Lucas Fish's posts, he is well aware that Dire Grove and some other titles do not run on Windows 7.
I'm sure this is not what you're looking for, but a potential alternative.
1. Manhattan
It's a cocktail, it's where S&G did their famous free concert, it's the setting for several animated films like Spiderman, TMNT, Secret Life of Pets, etc.
I finished Tormentum 1: Dark Sorrow. I liked the game but I did not know at the beginning that there were different ways to solve the puzzles and that I was being judged or tested so I ended up "bad" from the get-go.
I think I am going to play Nancy Drew #24: The Captive Curse next.
Somewhere along the line I retired; turned 80; and found myself with lots of time. As a result I can reload and play all my old favorites (The "syberias", most of the "Mysts", and especially "URU") for hours at a time. There are very few advantages to getting old, but that is one of them.
