Last week I wanted to play with my friends in Paragon as it was in open beta. All of us have downloaded the game through the Epic Games Launcher. Took a while but in the end I was not able to run the game because of system error – d3dx9_43.dll is missing from your computer, please reinstall the application to fix the problem. But it doesn’t specify what should I reinstall, the game or the launcher. Anyway after a few hours I found that reinstalling the game, neither the application doesn’t solve the d3dx9_43.dll is missing error. After wasting few days, me and my friends finally found the solution for d3dx9_43.dll is missing error in Paragon, which I will share below.
d3dx9_43.dll is missing error in Paragon appears upon launching as a result of corrupted or missed d3dx9_43.dll library, which is a part of DirectX and without it the game can’t be launched properly. If the reinstallation of DirectX doesn’t help, you can simply manually install the d3dx9_43.dll file. Download the library from here: http://fix4dll.com/d3dx9_43_dll. The installation instruction is provided on the downloading page or you can find it on that website. However, it is basically just copy and paste of the file into the proper location of system folder, depending what kind of operating system you are using. After that, simply reboot your computer and everything should work.
With this trick I was able to get rid of d3dx9_43.dll is missing error in Paragon. Hope it will be helpful for somebody too. Feel free to share this guide.
