Error: "The d3d11.dll file was not found". What to do?

Very often retro-gamers are faced with the problem of not being able to launch the executable file of the application, and the system reports that many incomprehensible d3d11.dll file was not found. What to do in this case, we now try to find out. At the same time we will consider some of the most probable causes of the appearance of a failure of this type and the simplest methods of correcting the current situation.

Why does the error "Can not find d3d11.dll"?

First, let's see what the missing file itself is, which is indicated in the error message. It is one of the main components of the DirectX platform and is responsible for processing graphics in Direct 3D mode (support for 3D modeling and textures).

Error d3d11.dll (execution of the internal code of the dynamic library) can occur not only in the absence of the desired file with this name, but also because of its damage, infection with viruses, incompatibility of the file version with the main DirectX package due to its replacement when installing gaming applications and . By the way, it's easy to guess by the filename that it's DirectX version 11.

Let's look at the situation when there is an error like "component d3d11.dll was not found". What to do and how to fix it? In principle, to date, there are several basic techniques to solve this problem.

Error "d3d11.dll was not found": what should I do?

To begin with, we note that there is nothing terrible or critical for the system as a whole here. The very question of how to fix the error d3d11.dll, in general, is solved in a few simple ways.

The simplest option would be to roll back the system to its original state, which was fixed at the restore control point before the problem manifested itself. True, there is one nuance. The point is that if you still want to use the installed application, the system will issue a similar warning again.

It should be noted that many old games designed for antediluvian video cards required installation of DirectX, compatible with them. It turns out that when installing a game the installer simply replaces the more recent dynamic library file with the old one, but the main components of the platform can remain unchanged. At the same time, it is not even determined that the platform itself has a higher version.

Download library file

As you might expect, the simplest way to eliminate such inconsistencies is to replace the installed installation file with the original version that corresponds to the DirectX package and the operating system's bit depth.

In this case, it all comes down to installing the game after downloading the necessary library from the Internet and placing it on the system drive on which the "operating system" is installed, to the address with the address Windows \ System32 \ d3d11.dll. When copying, you just need to agree to replace the original file. It goes without saying that after downloading the library from the Web, it should be checked immediately for viruses and malicious codes.

Reinstalling DirectX

The drawback of the above described method is only that the replacement of a single file does not exclude the possibility of errors associated with other libraries and components of DirectX. In this case, the most logical and simpler solution is to reinstall the entire package.

If you really decided to start the old game on the same "seven" or Windows versions above, the order of the actions is as follows: install the game, download the latest version of DirectX from the Microsoft website, install the package into the system and start the game.

If you consider the situation, so to speak, "on the fingers", it turns out that first the installation distribution kit replaces or changes the installed library, but after installing the new version of the platform, the dynamic library d3d11.dll is automatically replaced with the new version corresponding to the DirectX assembly. As a rule, after that almost all obsolete games are launched without any problems.

DLL Suite application

Among the solutions to fix this situation, you can also highlight the use of special utilities to automatically verify the integrity of the package DirectX and all its components.

Among them, the first place is occupied by the most powerful DLL Suite application. Working with him is easy. It is enough just to activate the scanning process, as the program immediately finds malfunctions and prompts you to download the missing components. True, the peculiarity of the application is that it will immediately find several dozens of files. In this case, you will need to select only those that correspond to your system (referring to the architecture of 32 or 64 bits). After installation it is desirable to overload the system, after which it will be possible to use the installed game.

Program DLL-Files.com Fixer

A little less "advanced" is the utility DLL-Files.com Fixer. Despite this, an ordinary user with her will be much easier to cope with.

Here, however, after checking the system for the integrity of components, you will have to use the search for specific libraries. In the search field, the name of the source component is entered, after which the program automatically finds it, and after loading it in the same mode integrates it into the system.

There is one "but" here. If there are several damaged or missing files, you will have to search, download and install them one by one, which will take more time.

Additional Actions

So, while we were sorted out with errors like "the file d3d11.dll was not found." What if the application still does not want to start?

As you know, not only games can affect the manifestation of such failures when running applications. Programs for processing three-dimensional graphics and animations that actively use the capabilities of Direct 3D, too, are prone to the appearance of errors of this kind. And they can not always be associated with the dynamic library files of the platform itself.

It may very well be necessary to update some additional components in the form of the Microsoft .NET Framework or the Java applet executable environment, Visual Basic, etc. But, as practice shows, in most cases this will not be required.
