Plutonium

I have commented in another post about the same topic but I did not get any answer about my problem, and now the comment section there is locked. So as I asked in the other post, I get this error, and no I am not running windows 7, I am running windows 8. In the other post you explained That you do not support windows 7 but you did not say anything about windows 8 and my problem. Can you please explain and help??

Mr. Android i am running windows 8

I have the same problem. Already have downloaded mw3 on steam, but it shows me the same error, anything else that I can do?
