[SOLVED] How to fix “D3d11.dll not found”

Definition

Before providing guidance on how to fix the error with the absence of the above library, it is worth understanding in general terms what kind of d3d11.dll error this is, because in any case it is necessary to understand what we are dealing with.

And, in principle, there is nothing to understand. The designation d3d11.dll refers to a dynamic library included in the DirectX 11 package. It is important to note that it is the eleventh version of the package, and no other. For example, if you download and install DirectX 9, the error will still occur because the system does not have the required library.

By the way, DirectX, and accordingly the d3d11.dll library, is responsible for the correct display of graphic models in the software. That is, we can already conclude that all programs or games that do not include any three-dimensional graphic models will run even if the library is missing.

In addition to the direct definition, it is also worth understanding the cause of the problem. Based on the context of the system message, you can already understand that the program or game cannot start due to the lack of the required library. But this does not mean that it was deleted. You could install it, but the antivirus, considering the file infected, could quarantine it, thereby preventing it from working.

We figured out what kind of d3d11.dll error this is, and this means that we can begin to use methods to eliminate it; fortunately, there are many of them, and each solution is good in its own way.

Method one: installing DirectX 11

While talking about what this d3d11.dll error is, we mentioned DirectX 11, that this package carries this very library. We can already conclude that in order to correct the mentioned error, it is necessary to install this distribution into the system. This is the first way to fix d3d11.dll.

The very essence of this method is simple: you need to download the DirectX 11 package and install it. And if no one has any problems with the second point, since the installation wizard will explain everything in detail, then there may be problems with the first. Of course, you can download DirectX 11 from anywhere, but it is recommended to do this from the official website, as otherwise there is a chance of picking up malware.

Now we will provide instructions on exactly how and where to download the package. By following it, you will absolutely not aggravate the situation:

1. Initially, log into any search engine.
2. Search for “download directx 11”.
3. In the results, follow the link whose address begins with “microsoft.com.”
4. On the system that opens, select the localization option for your OS from the list.
5. Click "Download".

After completing all five steps of the instructions, the process of downloading the package will begin. Rest assured that it is completely safe, so you can begin installation immediately. After this, all problems associated with the missing library should disappear.

Method two: using a special program

You can also resolve the error “d3d11.dll was not found” using the second method, which is much simpler than the previous one. This time, a special application DLL-Files.com will be used to download and install the required library. Therefore, before following the instructions below, you will need to download and install this program. This should be done from the official website to eliminate the threat of virus infection.

So, after you have installed the program, open it and follow these steps:

1. From the home screen, type “d3d11.dll” into the search bar.
2. Click Search.
3. Click on the library of the same name.
4. Click on the “Install” button.

After completing these steps, the error will disappear.

Bug fix

Fixing a function access error in d3d11.dll involves rearranging the library itself. DLL is executable code; you cannot enter such a file and edit it. Moreover, the file belongs to the 11th version of the DirectX package.

Thus, the first way to fix the error is to rearrange the DirectX 11 package. This method is simple and has been proven for a long time, the main thing is only to find a working version of the add-on itself, which is best done on the official Microsoft website.

Installing DirectX on Windows

Another way is to rearrange only the d3d11.dll file itself. This can be done using the specialized utility dll-files.com, which is free and available on the website of the same name.

So, install and run dll-files.

Searching for a DLL file in the DLL-files.com program

Enter “d3d11.dll” in the search bar. After the library is found, click “Install”.

Installing a DLL file in the DLL-files.com program

If you are used to doing everything yourself, then the problem can be solved manually - this is the third way. To use it, download the d3d11.dll file and place it in the desired system folder. Here you need to be careful, since this folder is different in different versions of Windows (in the examples it is assumed that the system is installed on the “C:” drive, if this is not the case, then the drive must be corresponding):

• in versions of Windows XP, Vista, 7, 8, 8.1 and 10 – C:WindowsSystem32;
• on Windows 95, 98 and Me – C:WindowsSystem;
• on Windows NT and 2000 – C:WINNTSystem32.

Let's take into account that if there is also a version of the system for a 64-bit processor, then the final folder for our file in any case is “SysWOW64”.

Copying a file into a folder does not ensure working with it. Now it needs to be registered in the Windows system registry. To do this, run the command through the command window (Start/Main Menu/Run): regsvr32 d3d11.dll.

Method three: manual installation

The error can also be resolved manually - without using any programs. To do this, you will need to download the d3d11.dll file itself from the Internet, and then move it to the desired directory. Unfortunately, the directory is different for different versions of Windows. Now the path to each OS version will be demonstrated:

1. Windows XP, Vista, 7, 8, 8.1, 10 - “C:\Windows\System32”.
2. Windows 95/98/Me - “C:\Windows\System”.
3. Windows NT/2000 - “C:\WINNT\System32”.

It is also worth taking into account that if you have a 64-bit OS, the final folder will be called SysWOW64.

Now you know not only what this d3d11.dll error is, but also how to fix it. Fortunately, there are three ways to do this.

Solution

It’s worth noting right away that the solution to the situation under consideration has an incomparably simpler form than searching for the causes of errors with a file. That is why you should start immediately with a possible solution. The point is simple. The “D3d11.dll” file is part of the “DirectX” package, which is known to every computer game fan. There is no point in going into details of the purpose and benefits of DirectX, since this topic has been studied far and wide. Based on the above information, we can make a logical conclusion that the best (and almost guaranteed) solution to this error is to update/reinstall the “DirectX” component. To do this, you need (for users with Windows 7) to visit the official Microsoft website in the “Downloads” section and download the installation file.

For those who use Windows 10, this action is not necessary, since this version of the operating system is characterized by the fact that most of the tasks of timely updating components, including DirectX, have been delegated to it. All you need to do is run Windows Update and initiate a search for missing components. As an alternative, you can use various third-party applications that allow you to uninstall DirectX, and then simply launch Update Center. If the above recommendations do not have the desired effect, it is worth trying a slightly different approach.

ADVICE. But it is worth warning that you need to be wary of any recommendations (of which there are a huge number on the Internet) that would advise downloading the “D3d11.dll” file from third-party resources (especially from file hosting services) or using “special” utilities that allow you to automatically scan system, download and register dll files. At a minimum, it will be wasted time, and in most cases, problems with the operation of the computer will only be aggravated. The error in question can and should be resolved exclusively using proven methods.

So, the previously announced alternative approach is relevant for all situations where an error with “dll” manifests itself when starting and using software (games, applications, etc.). The bottom line is that most copies of gaming products (obtained in a not entirely legal manner) contain their own copies of libraries that are necessary for their operation. And if these components were damaged during the installation process (or during the assembly stage of the “repack”), then when accessing the missing files, the system will generate errors.

In order to check this, just find the folder where the game/program was previously installed and find the root directory where such files are contained (the name of the folder will depend on the software). After you make sure that the required component is present there or not, move the correct “D3d11.dll” file that you received after installing/updating “DirectX” to the root directory, from the old file (if any) It's not worth getting rid of. Just move it to another folder.
