Few days ago the xinput1_3.dll is missing error started to appear every time I tried to launch Steep game purchased on Steam. I had no idea why it is happening and I was sure that it is some kind of virus or something. After scanning my computer with anti-virus software I realized that I don’t have any virus, but the xinput1_3.dll is missing error still persists. It was bothering me for quite long time until I found a working fix that I will share below. But before that I will tell you that I wasted lots of time searching for the solution and tried various fixing guides, some of which even included registry modifications and other things that will be quite difficult for ordinary computer user.
