Win 7, Go or No

Hi,  I've been playing GalCiv 3 for a long time now and when I a saw that 4 had gone to beta I got all exited.  Then I read the specs and minimum was Windows 10.  I'm still running a Win7 machine and am not in a position to upgrade at this time.  The Hardware is up to the task though.

So the question is will it run on 7 or is it totally incompatible?

Thanks
