The EN installer should be smart enough to detect that my system is running Windows 7 and does not proceed from there. That is what most (probably 99.9999%) installers do. Anyway, I manage to find and install version 10.43.7 and it's running fine.
As for Windows 10, no thanks. I had it on my laptop and it's trash. I have been using Windows 7 since its release and had zero security issue.
Thanks.
