it isnt cracked game and i must have original??

Doesn't matter, as long as you don't put crack into game folder. I downloaded MP only and it works fine.

You need to buy the game or use google/youtube to find the 'crack'

but i have window that i must run steam

i think it was cracked before gamecopyworld?

but i have window that i must run steam

You'll have to be more specific.

Run steam and then read the error and do what that error says.

Error during initialization:

Your current Steam account does not own Call of Duty: Modern Warfare 3. Please purchase the game, try another Steam account or make a folder called 'dw'.

Make the folder in your IW5 games folder.
