4-MX try to run on a mac M2, under monterey

Hello,
I got out my 4-MX controller that I'm trying to run on a macbook air M2 under monterey (12.5). I installed the 6.51 package but the firmware remains at 1.1.12.14, but I read everywhere that you need the .16 at the end ... where can I find it? Can't find package 6.44 either
(I was using it under win7, when I bought it)

I found this old post, but it's archived
