Battlefield 3 is the classic shooter, which is in my honest opinion is the best in Battlefield game series. The game is pretty old; however, it still has lots of servers to play on and it is very optimised, which is cool for old computers like mine. I was getting stable 60 fps when played it few months ago. Anyhow, yesterday I installed it once again through Origin launcher and tried to launch the game, but to my surprise I got a system error stating that d3dcompiler_43.dll is missing from my computer and I need to reinstall the program. However, after reinstalling the game I still couldn’t launch it because of d3dcompiler_43.dll not found error. Luckily, the game community is very large and within few minutes I was able to find some fixing solution on EA forum.
Initially I didn’t want to use any third-party software to fix the d3dcompiler_43.dll is missing issue, so I opted to fix it manually by installing the library into my system folder. As it is a system library, you have to be careful where you downloading it from, because some cyber criminals can take advantage of that and penetrate your computer with malicious file. Anyhow, I have downloaded genuine d3dcompiler_43.dll library from: https://fix4dll.com/d3dcompiler_43_dll and installed it by following the instructions on the website. After rebooting my desktop, the d3dcompiler_43.dll is missing error has gone and I was able to launch the Battlefield 3 without any issues. Feel free to use this guide and share it with your friends.
