X3DAudio1_7.dll Error: Fix for Windows 10

In today’s post we will learn how to fix the X3DAudio1_7.dll missing DLL file error on Windows 10, in a simple and efficient manner

Have you dowloaded a new game and got an error just after you launched it the first time? This can be frustrating and it the X3DAudio1_7.dll error actually happens in a lot of games running on Windows 10.

Let’s analyze what is this file for, and how to fix it when you have this error on Windows 10.

What is the X3DAudio1_7.dll file about?

I recently got one of the best driving simulators around, called City Car Driving. After watching a lot of videos about the game, I had finally decided to get it. It has a lot of car mods and I was very excited about it. After installing it, I was surprised by an missing DLL Error.

A missing DLL error message cut my excitement short. It indicated that the X3DAudio1_7.dll was missing. I wouldn’t be able to enjoy City Car Driving that soon.

After browsing a bit on the internet, it seems that the X3DAudio1_7.dll is a DirectX 9 file. However, I only had the DirectX 11 on my Windows 10 version.

How to fix the X3DAudio1_7.dll missing DLL error

After knowing more about the file, I came to know many games need it to run. Not only City Car Driving requires it, but some other games like The Witcher 3, Skyrim, Fallout 4, Paragon, BeamNG and many others appear to have the same issue at all.

Solution 1:

The first solution I came accross was simply to download a couple of dll files and paste them on your Windows System dirs. I tried this on Windows 10 and it didn’t work. Even if the error message changed. It still wouldn’t launch the game.

This time the message box indicated a 0xc00007b error.

Solution 2: The one that really works

After browsing more about the internet, I came across a German software development responsible for a program named AiO. AIO stands for All in One runtimes, and it installs a number of useful runtime pages, including .NET and DirectX files.

You can download All in One runtimes from Sereby.org. Once you download it, even if its in German, just click Installieren or Install. In the photo above, you can see how it looks like, the .NET and DirectX are not listed there, since I have already installed them.

That’s it, now you can fix both the X3DAudio1_7.dll missing error and the 0xc00007b error. Enjoy your gaming.
