Check both system reqs for it and the computer specs... If you need to (I think Darwinia is Steam)You might need to get a new version of steam just go to ValveSoftware
and download steam... Steam
... that website also might work, not sure though.
Edit: SteamOnline (2nd link) is not what it used to be so don't click it.... TRUST ME... You'll be corrupted for life.
