I do run my factorio through steam. Sadly, none of the replies so far has come up with a solution so far.

I bought a copy of Factorio ages ago and ran it smoothly on my PC, after a while i opgraded to Windows 8.1 from Windows 8. Now I manage to get the error where I have to download windows 7 service pack 1.
I tried to figure a way to do it but it doesn't seem like it is possible.
