Salut,
Les devs ne parlent que de Windows 10 car ils disent que c'est la seule version de Windows encore supportée par Microsoft.
Le jeu fonctionne bien sous Windows 7.
Windows 7
There was confusion (including here in the office) about whether the game will run on Windows 10 only or on other versions of Windows as well. Officially, we use the term “Windows 10” everywhere, because older versions, including Windows 7, are no longer supported by Microsoft and some middle-ware providers, or their support might run out before Iron Harvest is released.
BUT Iron Harvest currently runs just fine on Windows 7 and we don’t see a reason why it shouldn’t do so in the future.
It’s just that Microsoft and others keep talking about not supporting it anymore, so it’s a somewhat uncomfortable position for us as developers. So… it IS a Windows 10 game, but it will most likely run on Windows 7, 8 and others versions as well.
