How to fix d3dx9_43.dll is missing in League of Legends

Everything was fine till yesterday, when I tried to launch LoL client it started to give me d3dx9_43.dll is missing from your computer, try to reinstall the application to fix the issue. I’ve tried to reinstall the game, but it didn’t help. I found similar topics on Microsoft website and the support team advised to reinstall DirectX, which I also tried, but it didn’t work for me. I was playing for rank with my friends and they couldn’t wait for long so we all united our searching skills and started to look for the solution on the Internet.


After a while we have tried many solutions on my computer and nothing worked. Updated drivers, reinstalled programs, the only thing left was to reinstall the Windows, but I didn’t want to do that, because I don’t have any external hard drive to back up my personal files. But it looked like the only option to fix d3dx9_43.dll is missing error. Anyway, today I went to check my topics on forums and found one response from old veteran of LoL. He advised me to simply download and install the missing d3dx9_43.dll file and it won’t bother me again. So, I went to the :, downloaded the file and followed the installation instruction that I also found on the website. After that I rebooted my computer and miracle happened: the system error d3dx9_43.dll is missing from your computer has gone and the game launched without any problems.

I managed to fix d3dx9_43.dll is missing error in League of Legends without reinstalling windows. Wish I knew this fix before, I lost few days of playing with my friends.
