What is D3DCompiler_47.dll?

D3DCompiler_47 is a component of DirectX, which is a platform developed by Microsoft, intended to deal with multimedia tasks, such as games, on Windows systems. This file may be missing because it is accidentally deleted when you remove a program. But in some cases, it can become corrupted because of your wrong device drivers.

What to do if D3DCompiler_47.dll is missing?

Here are the methods you should try when you see the D3DCompiler_47.dll is missing error. 

  1. Update your device drivers
  2. Update your Windows
  3. Reinstall your operating system


1. Update your device drivers

You may get this error because the driver you use are wrong or out of date. You can try updating your drivers and see if this resolves your problem.

You may need plenty of time and energy to find the correct drivers and install it on your computer. You may need a tool to do all the jobs for you.

Or running the driver installer will incur your D3DCompiler_47.dll missing error. You will need an alternative method to get around the error and update your device drivers.

In either case, using Driver Easy is a recommended option.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing.

You can download and install your drivers by using either Free or Pro version of Driver Easy. But with the Pro version it takes only 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and Install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to each of your devices to download the latest and correct driver for this device. You can also click the Update All button at the bottom right to automatically update all outdated or missing drivers on your computer (this requires the Pro version — you will be prompted to upgrade when you click Update All).

4) Restart your computer, then check to see if the error’s gone.

2. Update your Windows

When you see a component of DirectX missing, you may be thinking that you can get it back by reinstalling Direct X. However, DirectX (DirectX 10, 11 and 12) has been included in Windows systems since Windows 7. There are no standalone installer released by Microsoft that you can use to reinstall and repair DirectX.

But you can repair the component by updating your operating system. There are some system updates intended to update the DirectX feature and can help you repair this feature. Also, Windows has released an update specifically for fixing the D3DCompiler_47.dll missing error (for Windows 7). You can try installing these updates and see if your problem is resolved.

To update your system:

1) Click the Start button. Then type “update“. When you see Windows Update appear in the list of results, click this result. This will open Windows Update.

2) In the Windows Update window, click Check for updates.

3) Install updates if your computer is not up to date.

Note that if you are on Windows 7, there are two important updates you should install because they are very helpful for fixing your problem. They are KB4019990 (released by Microsoft specifically for this error) and KB2670838 (to update your DirectX). Download and install them on your computer and see if they can help. (Make sure you have installed the Service Pack 1 of Windows 7 before you install these updates.)

3. Reinstall your operating system

As mentioned in method 2, you can’t repair your DirectX by simply reinstalling it with a standalone DirectX installer. When updating your system can’t help you get your missing DirectX file back, another way you can try is to reinstall your operating system. This can be considered as a way of reinstalling your DirectX.

Back up your personal documents and data on your system drive (C drive usually). Prepare a Windows installation media and put it into your computer. Then run the media and follow the instructions to reinstall your operating system.
