Finally, today, during the black Friday I purchased the Call of Duty 4: Modern Warfare Remastered game. After downloading the game, I tried to launch it, but nothing happened. So, I tried to launch the .exe file in the steam installation folder and then I got system error stating “The Program can’t start because xinput1_3.dll is missing from your computer. Try reinstalling the program to fix this problem”. Well, I tried to reinstall the COD MW, but it didn’t fix the problem. After contacting the steam support and game developers I received unpleasant answers that the problem is not with game or steam application, but with my computer and, as always, they suggested to update drivers and all that stuff. I started looking for the solution on the Internet and discovered that a lot of users like me having xinput1_3.dll is missing error when trying to launch Call of Duty 4: Modern Warfare Remastered.
After a while I found some solutions for xinput1_3.dll is missing error in COD MW, but none of them worked properly, some even suggested to install some third party applications which were detected as a threat by my antivirus. Anyway, by the end of the day I finally found the working solution and it doesn’t require any IT knowledge neither installation of third party software. So, what I did is just downloaded the missing xinput1_3.dll file from here: http://fix4dll.com/xinput1_3_dll and installed it by following this instruction. Don’t forget to back up your original file, if you have it. After that I simply rebooted my computer and Call of Duty Modern Warfare has started to work without any error
Hope I have helped you to fix xinput1_3.dll is missing error in Call of Duty 4: Modern Warfare.
