Mw3 wont launch from steam

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name provide the model name or series number (not serial) if a custom build post the brand and model name or number for the following:

OS
CPU
Motherboard
RAM (including the amount and Number of Sticks)
Add on Video Card if one is used
Power Supply Unit

Providing these details will enable folk to better help you.

So other can assist let get a speccy report.

Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Let's see if there are any error message that can be pulled by the MinitoolBox.

Download MiniToolBox and save the file to the Desktop. Right click on the file and select Run as Admin

Close the browser and run the tool, check the following options.

Select all

Click on Go.

copy and paste the contents of the file called MTB.txt or attach the file to your next post.

Once you follow @Rustys 's instructions, let me know if you have verified the integrity of the game files within Steam.
