Fix 1: Restore the X3DAudio1_7.dll file

If X3DAudio1_7.dll is missing or not found in your computer, you can fix your problem by restoring the missing file in your computer. Here’s how:

  1. Go to DLL-Files. Use the search box to look for the DLL file that is missing from your computer.
  2. Once it got a hit in the database, you will see the available dll files. You can then click the file and follow the instruction on the page to download the file to the designated location.
  3. Note that sometimes you may find that there are multiple files available. Mostly you can simple pick the highest version. But when the versions are the same, it could mean that the files work for different architecture. To find out the architechure of your system (whether it’s 64-bit or 32-bit), you can open Windows Settings and check the System type.
Missing DLL files could imply a bigger issue, and sometimes on the system level. If the problem persists, you can use a system repair tool like Fortect to scan for system issues.

Once install, check if your x3daudio1_7.dll missing problem has been fixed.

Note: It’s recommended to download and install the dll files from official website, and do not install the dll file from unknown source to avoid internal corruption and potential risks.
  1. Go to Windows End-User Runtimes download page.
  2. Select the appropriate language, and click Download.

  6. Reinstall the program and launch the program.

Fix 4: Copy the file from another computer

  1. Find another computer that runs the same operating system as yours.
    The versions (Windows 10/8/7) and architectures (32-bit/64-bit) of both operating systems must be the same.
  2. On that computer, open File Explorer (by pressing the Windows logo key

     and E on your keyboard), then go to C:WindowsSystem32 and copy the X3DAudio1_7.dll there.
  3. Paste the copied file to the same location (C:WindowsSystem32) on your own computer. (You may need an external storage device, like a flash drive.)

Try launching the application again and it should be working.
