I was invited to participate in closed beta of For Honor from Ubisoft. After installing the game, I tried to launch it, but the game wouldn’t launch. Only the game window appeared and then nothing happened. After the reinstallation the same problem remained. I’ve tried to check the Windows error log and found that I was getting xinput1_3.dll is missing from your computer error. The reinstallation of drivers and DirectX didn’t help me, so I started to check the Ubisoft forum for some proper solution. However, since the beta was released today, there is not so many information about it. Anyhow, I have tried the old method that I applied in previous games and it worked.
So, to fix xinput1_3.dll is missing error in For Honor I just had to download xinput1_3.dll file from here: https://fix4dll.com/xinput1_3_dll. After downloading the file, I scanned it with antivirus just to make sure that it’s not some kind of virus and by comparing md5 file sum I found that the file is completely genuine and safe to install. The installation process is well described on the website and it is quite simple. All you have to do is to copy the file into the proper location on the system drive. After installing xinput1_3.dll in the system folder and registering it in the system I was able to run For Honor and play it.
Hope this will help you to fix xinput1_3.dll is missing error in For Honor Beta. Feel free to share this guide with others.
