I figured it would work, because a user had the exact same problem as you. I asked him to test that trick (I was confident it would work because of how Godot works), telling him I wasn't sure it would work, but that was worth a try. And it worked (it's a hack, it's not the same as a cleanly released MM for 32 bits Windows).
So I just let this as a possible solution. I'm not sure it will work for everyone, but if it does work for you, it's great. But if it did not, I just could not help you.
So I'd rather make it clear it's not supported, so users are not mad at me because I release untested software.
