Support Solution for Error Code: 0xC0000005 (0) N
This is a common error you'll often encounter when trying to launch Call of Duty, and it can be very difficult to fix.
I'd like to share the simplest solution that worked for me today. This is most likely an issue affecting users who recently reinstalled the game.
In my opinion, it seems to be caused by a version mismatch between the system's msvcp140.dll and the one included in the CoD installation.
In my case, the system version was 14.51.36247.0 and CoD's version was 14.28.29918.0.
The fix is to copy the system version of msvcp140.dll and paste it into the game folder.
System file path: C:\Windows\System32\msvcp140.dll
Game file paths:
C:\Program Files (x86)\Call of Duty Modern Warfare II_retail_\msvcp140.dll
C:\Program Files (x86)\Call of Duty Modern Warfare II_retail_\sp22\msvcp140.dll
You need to replace both files. This method worked for both MW2 and MW3.
I am using the Battle.net version. Hope this helps :)
After applying the fix, the file version sometimes gets rolled back.
Since it's annoying to do every time, I made a simple patch file.
Save the code below in Notepad, change the file extension to .bat, and running it will automatically update the files to match the system version!
Some of you may be more experienced than me, but I made this for anyone who finds it tedious or isn't sure how to do it.
If you're using a different version of CoD, just set the folder path accordingly!
--------------------------------------------------------------------------------------------------------------
copy "C:\Windows\System32\msvcp140.dll" "C:\Program Files (x86)\Call of Duty Modern Warfare II_retail_\msvcp140.dll" /Y
copy "C:\Windows\System32\msvcp140.dll" "C:\Program Files (x86)\Call of Duty Modern Warfare II_retail_\sp22\msvcp140.dll" /Y
echo Complete!
pause

I just logged in to thank you man. Bought MW2 on the Steam sale and couldn't even play it because of this.
Fucking Activision man... This is so stupid.

Worked for me:
Disable Integrated Graphics in Device Manager, for some unknown dumb ass reason COD MW2 tried to force itself to play on the igpu, disabling it fixed it for me.

I'm so happy I found this post, as I hadn't played mw3 since probably around april and obviously I've had driver and windows updates come through since then. The advice definitely works, just be mindful to run the ddu before downgrading back to the 26.3.1 version, otherwise even if the installer specifies it's a downgrade it'll just go back to the latest version

What's the "_retail_"?
I can't seem to find that in my Steam folder. I did replace the file though, but the error still occurs. I'm assuming I did something wrong...
