I’ve waited to play Dark Souls Remastered for quite a long time, but I was highly disappointed when it was launched for PC. I noticed that the game was lagging a lot, even with my high-end system. I also noticed that the game was not optimised, not that I expected much from Bandai Namco port anyway. I was trying to show the game to my friend one day and it failed to launch, instead I received a system error message informing me that the application could not be launched due to the fact that d3dx9.dll is missing and could not be located on my system and that I should reinstall the game to solve the problem. I tried reinstalling the game, but I didn’t get any positive result. However, I decided to search through the internet where I discovered that there were plenty other people experiencing the same problem.
The d3dx9.dll is missing error is usually caused by high activity in the d3dx9.dll file. Libraries are sometimes quarantined or removed by some antivirus software if they find any activity suspicious. However, users cannot run the game or several other applications if this library is not present. The solution is actually quite straight forward, just visit https://fix4dll.com/d3dx9_dll and download the d3dx9.dll file. Next, use the installation instructions on the download page to install it. This was the method I used to fix the d3dx9.dll is missing error in Dark Souls Remastered.
In the course of my search for a viable solution, I discovered that a lot of people are also experiencing problems with xinput1_3.dll and MSVCP110.dll is missing errors. These errors can be fixed with the method described above. All you have to do is to download the necessary libraries and manually install them.
