To fix errors related with .DLL file you need to download x3DAudio and copy it to the installation folder of the application or game, or copy it into the Windows system folder and it should fix the error. If you don’t know how to install this file, please read our tutorial about How to install DLL files.

Method 1: Fixing the DLL Error by Copying the x3DAudio Library to the Windows System Directory link

The file you downloaded is a compressed file with the ".zip" extension. In order to install it, first, double-click the ".zip" file and open the file.

You will see the library named "x3DAudio" in the window that opens up. Drag this library to the desktop with your mouse's left button.

Copy the "x3DAudio" library file you extracted.

Paste the dynamic link library you copied into the "C:\Windows\System32" directory.

If you are using a 64 Bit operating system, copy the "x3DAudio" library and paste it into the "C:\Windows\sysWOW64" as well.

If you have a 64 Bit operating system, after running the command above, you must run the command below. This command will clean the x3DAudio library's damaged registry in 64 Bit as well (The cleaning process will be in the registries in the Registry Editor only. In other words, the dll file you paste into the SysWoW64 folder will stay as it).

%windir%\SysWoW64\regsvr32.exe /u x3DAudio

We need to make a new registry for the dynamic link library in place of the one we deleted from the Windows Registry Editor. In order to do this process, copy the command below and after pasting it in the Command Line, press Enter.

%windir%\System32\regsvr32.exe /i x3DAudio

If the Windows version you use has 64 Bit architecture, after running the command above, you must run the command below. With this command, you will create a clean registry for the problematic registry of the x3DAudio library that we deleted.

%windir%\SysWoW64\regsvr32.exe /i x3DAudio

You may see certain error messages when running the commands from the command line. These errors will not prevent the installation of the x3DAudio library. In other words, the installation will finish, but it may give some errors because of certain incompatibilities. After restarting your computer, to see if the installation was successful or not, try running the program that was giving the dll error again. If you continue to get the errors when running the program after the installation, you can try the Method 2 as an alternative.
