There have already been many articles on the topic of errors related to DLLs. All these errors can be corrected in the only way - by installing this very dll file on the computer. In this article I will write how to do this.

Downloading and installing DLL files

When an error occurs, the name of the DLL file that is missing is usually indicated. You need to enter the name of this file in a search engine and download. For example, we need to download the file d3dx9_27.dll. We enter this name in Yandex or Google and download it from some site. The most secure and popular site from which I download DLL files myself is DLL-FILES.com. There is a field where you can enter the name of the file.

Now you need to figure out where to throw this dll file. IN different systems The locations of these files are different, so I'll start with the early OS:

• Windows 95/98– place the file in the folder C:\Windows\System;

• Windows NT or 2000– place the file in the folder C:\WINNT\System32;

• Windows XP, 7, 8, 10– place the file in a folder (for 32 bit systems in C:\Windows\System32, and for 64's bits in C:\Windows\SysWOW64).

Sometimes when trying to place a file in the desired folder a message may appear that the file is already there. Then why does the error appear? It is possible that the file is damaged or it is some kind of virus, so you can replace it with a new file.

Once you have transferred all the missing libraries, you must restart the computer for the changes to take effect, and then launch those applications that did not work.

What to do if you threw everything away necessary files to the folder, but the program or game still won't launch? Then you can try to register the library in the system, now I’ll show you how to do it.

How to Register a DLL on Windows

Registering DLLs in Windows is very easy and fast. You can do this if you have Windows 7, 8 or 10. I also want to note that you must have administrator rights. In this paragraph I will show 3 ways to register dynamic libraries.

First way

It is the most popular and used by users.

Open the “Run” window using the keys Win+R and enter the command regsvr32.exe file_name there.

In other words, the command might look like this (I’ll show it using the d3dx9_27.dll file as an example):

regsvr32.exe d3dx9_27.dll

If the method did not work, then you need to specify the full path to this file, that is, the path to the folder where you placed the DLL. For example, it might look like this:

regsvr32.exe C:/Windows/system32/d3dx9_27.dll

If registration is successful, you should see a positive response or an error message that module loaded... But I'll talk about this a little later.

Second way

Here we will use the command line, but you need to open it as an administrator, I hope you know how to do this.

regsvr32.exe path_to_dll_file

That is, we do everything the same, only on the command line.

A message should appear again that the library is registered, or an error.

Third way

The method is rarely used by anyone, but it also works. Take your dll file and right-click on it, in the appeared context menu select an item "To open with" and go to the folder Windows/System32, and look there for the program regsvr32.exe, through which we will open the library.

Error registering DLL files

When you try to register a DLL, no matter in what way, you may receive an error that the module of such and such DLL is incompatible with the Windows version, or is loaded. What to do?

Such errors may occur for the following reasons:

• The library does not need to be registered because it does not support this feature or is already registered with the system;

• The file you downloaded is broken or completely unrelated to the libraries.

How to solve a problem?

• Advanced users can use regasm.exe;

• Try downloading the same file on the Internet, only from a different source. Or look at what the file is and use special DLL file installers. Some libraries come with some kind of software, for example DirectX.

• When downloading an application, the antivirus might have deleted important DLLs that were in the installer during the installation process, so you need to download the game from another source, or temporarily disable the antivirus and reinstall the application.

At this point I will finish describing the installation of DLL libraries and in the future I will try to return to this topic as rarely as possible. If you still have any questions, I will try to answer them in the comments.

A DLL file is a component of a dynamic link library whose elements are used by almost all programs. The DLL files are located in the system root folder. The components must all be present, digitally signed, work correctly and be up to date with the version. If one of the requirements is not met, the user will receive an informational notification when starting the program: DLL error. The malfunction indicates that the DLL file is missing, damaged, or outdated.

How to install a DLL file

In order for programs, applications and games to start working again, you must manually install the missing library components. Simply placing a file in a folder is not enough ─ you need to know how to register them.

Placing and registering library files

Before installing a DLL file on Windows 7,8,10, you need to download them, and exactly for the system bit depth.

Let's determine what bit capacity your system has (if you know for sure, you can skip this step)

Step 1. Right-click on “My Computer” and select “Properties”

Step 2. In the window that opens, we can read the properties of the computer, the version of the operating system and its bit depth 32 (x86) or 64 bit. In our case, we have a 64-bit Windows 10 operating system.

·

Step 3. After downloading the files, they need to be placed in the root folder and registered

for x32 (x86) systems, the component must be replaced or placed in the C:\Windows\System32 folder;

for x64 you need to replace it or move it to the C:\Windows\SysWOW64 folder;

Step 4. The file must be registered in the system.

You can do this by opening command line using the combination “Win” + “R”, or click “Start” and “Run”;

in the window that opens, enter the following, separated by a space: regsvr32 file name.dll – where, “regsvr32” is the command for registration, and “file name.dll” is full name inserted component;

or you can specify the file location manually - regsvr32.exe + file path

Step 5. Click "OK" and restart your computer for the new settings to take effect.

I would like to note right away that errors may occur during registration. For example: "Failed to load module." They usually occur for 3 reasons

1. The path to the file is incorrect, or the file was not moved to the System32 or SysWOW64 directory
2. Not all DLL files need to be registered at all; sometimes it is enough to simply copy them to the System32 or SysWOW64 directory or place them in the root of the problematic game or program
3. The files have already been registered before

Second registration method

Step 1. You can register the file using a command line, which must be run as an administrator.

Step 2. Writing a command regsvr32.exe + file path and press "Enter"

Step 3. A message will appear saying “Everything went well”, and just restart the computer

That's all, the file is registered, you can try to launch your game or program

Here are some tips that may be useful to you.

• Place items only in the specified folder (it may be hidden by default). You need to uncheck the "Do not show" hidden folders» in display settings.
• If administrator permission is required when replacing a file, confirm the action.
• Select only the files that are relevant at the time of downloading and save them to your computer separately. They may still be useful to you. If the problem occurs again, you will quickly restore system functionality.
  

The thought of downloading libraries for Windows 10, as a rule, comes in those moments - when something in the OS does not work, or some application or game does not start.

Peculiarities

There are no universal libraries; in this case, you need to reinstall the entire system. But very often it happens that the root of all problems lies in the fact that there are no Microsoft Visual C++ libraries on your computer, laptop or tablet, and if you download and install them, the problems will be resolved. These libraries are responsible for:

• Correct operation of the OS itself;
• Ability to launch programs and games;

It turns out that one small file (only 11.5 MB) brings so many problems, but at the same time, it also solves a colossal number of difficulties. To avoid mistakes, before downloading libraries, check which one you have Windows version 10. This page contains a version for 32-bit OS. There is also an option for 64-bit Windows 10.

To install libraries, you not only need to download them, but also unzip the file. Or a popular program will help you with this. After installing the libraries, you will no longer see , since these programs are executed in background, and the most important thing for you is installation, then the software works independently. So it doesn’t matter that the program is not in Russian. It is important that it is in the latest version, fresh and relevant.

Read, how to repair failed DLLs in Windows 10, 8 or 7. What are the causes of damage, deletion or errors of DLL files. DLL files themselves are not executable files, but they are used by other programs. Often, several programs or drivers can share a DLL file, so uninstalling or updating one program may break others.

If you receive messages: "DLL file not found or missing", "failed to register DLL library» , "a required component is missing" or "The application needs to be reinstalled", then our instructions will be useful for you. Such messages may occur during the launch of any application or game, during installation, update or startup of Windows 10, 8 or 7.

If you are unable to start the system due to an error in normal mode, use booting in safe mode.

Possible causes of damaged, deleted or DLL file errors

1. Unintentional deletion of DLL files by mistake.
2. Overwriting system DLL files with outdated versions.
3. Infection with viruses or malware.
4. Damage hard drive.
5. Missing or damaged hardware drivers.
6. Windows contains incompatible versions of files that belong to different applications.
7. Lack of necessary Windows components: DirectX, C++ Runtime Library, .NET Framework.
8. Automatic updates Windows and system drivers.
9. Using outdated or incorrect drivers.
10. Damage or deletion of critical registry branches.

Ways to recover DLL files in Windows 10

If Windows has stopped booting, or system files have been damaged or deleted, you can use recovery environment tools.

Also in Windows 10, 8 or 7 there is a tool for automatic recovery system files or libraries from the command line.

Errors related to missing required DirectX or C++ Runtime Library are the most common problems in Windows.

You need to install a compatible DirectX version, if the game crashes with the error: “The program cannot be launched because the DLL file is missing on the computer. Try reinstalling the program”, or the error text indicates the following libraries: d3dx9_43.dll, xinput1_3.dll, d3dx9_31.dll, d3dx9_34.dll, xinput1_2.dll, d3d11.dll, d3dx9_35.dll, dxgi.dll, d3dx9_25.dll, d3d11.dll, d3dx9.dll, dll, d3dx10_43. dll, d3dx9_26.dll, d3dx9_30.dll, d3dx9_27.dll, d3dx11_43.dll, d3dcompiler_43.dll, d3d10.dll, xinput1_3.dll, d3dx9_31.dll, xinput1_2.dll, d3dx9_31.dll, _34.dll, d3dx9_42.dll, x3daudio1_7.dll, x3daudio1_6.dll, xrsound.dll. To do this, you need to use the DirectX Web installer from Microsoft.

Install the required version of the C++ Runtime Library if the error text contains libraries containing the words MSVCR or RUNTIME: MSVCR120.dll, MSVCP120.dll, MSVCR110.dll, MSVCP110.dll, MSVCR100.dll, MSVCP100.dll, MSVCR90.dll, MSVCP90.dll, MSVCR80.dll, MSVCP80.dll, VCRUNTIME140.dll, runtime-x64.dll, runtime-x32.dll, runtime.dll, runtime-110.dll, etc.

Find in system requirements to the program which version of the C++ Runtime Dll libraries is required for operation and install the required one:

1. Reinstall the program that references the DLL file. The cause of the DLL file error may be an error in the operation of the program that uses it.

   Update the driver for the device that is causing DLL error file.

   
   

2. Check your computer for viruses. Some malware can take the form of a DLL file and cause an error in the computer.

   
   

3. Perform a system restore, returning it to the latest working version. Launch window Execute by pressing the keyboard shortcut Windows + R and enter the command in it: rstrui.exe

   
   

   When the System Restore Wizard starts, select the required system restore point with a date prior to the date the DLL errors started occurring.

   
   

4. If you accidentally delete a DLL file, it does not disappear from your hard drive - it can be restored from the Recycle Bin. Check Windows Recycle Bin, you may find your DLLs in it:

   
   

5. When permanent deletion file from the Recycle Bin, it is still possible to recover it. IN Windows files never disappear without a trace, they simply occupy the space on the hard drive (or other storage medium) that is marked as one on which new information can be recorded. In cases where DLL files are removed from Shift+Delete And standard means operating system it is no longer possible to return them, the most effective way would be to use the program Hetman Partition Recovery.

   For this:

   • Download the program, install and run it. Check out the program's capabilities and step-by-step instructions.
   • By default, the user will be prompted to use File Recovery Wizard. Pressing the button "Further", the program will prompt you to select the drive from which you want to recover files.
   • Double click on the disk and select the analysis type. Specify "Full Analysis" and wait for the disk scanning process to complete.
   • After the scanning process is completed, you will be provided with the found files. Select the ones you need and click the button "Restore".
   • Select one of the suggested ways to save files. Do not save files to a disk from which they were deleted - they can be overwritten.

   
   

6. Find and copy the required DLL file from another computer or installation disk. There are also DLL archives on the Internet that you can use to find the required DLL file configuration. However, we recommend installing libraries from official sites whenever possible.

Were you able to recover the DLL files? Leave feedback and ask your questions in the comments.

DLL format files open special programs. There are 2 types of DLL formats, each of which opens different programs. To open the desired type of format, study the file descriptions and download one of the proposed programs.

.DLL file extension

The HELPER.DLL program will help you find and install any missing or damaged DLL library.

DLL format files contain settings for links to various resources used by the program, for example, icons. DLLs are intended exclusively for Windows OS. On other operating systems, such files can only be opened using emulators (the exception is cross-platform applications for Mac OS). It must be remembered that modern programs do not support files for 16-bit architecture.

Precautionary measures

In most cases, the user does not need to open DLL format files as they are intended exclusively for developers. Editing of this file may negatively affect the performance of individual programs and the operating system, for this reason you need to find the Dll file and make a copy of it.

Programs for opening DLL files

View source code

One of the most common ways to view a Dll extension is . The program has built-in functions for decompiling some files, so you can debug dlls, and most importantly, it is completely free. Of course, it is impossible to guarantee correct display of code for all files.

As an alternative, you can use the dotPeek decompiler. It is also free, but can only work with programs written in C#.

Setting up the program interface

Best suited for this purpose. With this program you can easily change icons, dialogs or set your own animation. Unfortunately, the program is paid even for non-commercial use. Please note that problems may arise with large files (about 1 GB or more).

Debugging

The most in a simple way is to use Visual Studio from Microsoft. This is a fairly functional tool, the capabilities of which include program debugging, but it will only help if the file is not protected.

If you just need to download a DLL to replace a broken file (or a DLL is missing), then DLL-helper will help here - a completely free program.

Dynamic web pages

There is another DLL format - files that generate code for websites. Such libraries can be opened in any convenient development environment, for example, Visual Studio. The browser will help you test them in action. Better to use latest versions popular browsers, otherwise the file may not be displayed correctly.

A web page that is automatically created during user access. Can combine server-side scripts, such as Perl or , that generate code for web pages.

Web pages in DLL extension files are most often stored on Microsoft IIS web servers. The DLL extension must be mapped to the appropriate server scripting engine for the page to be processed correctly.

A compiled library file containing a set of procedures and/or drivers referenced and executed by a program. Allows various programs to access publicly accessible system functions through standard libraries. Can be dynamically linked within a program while it is running.

Many DLL files (read DLL) are provided operating system Windows, others included Windows programs. They also provide various software features such as connecting to external devices and the input and output signal of the hard disk. They can also be referenced by cross-platform Mac applications.

Note: Deleting or changing the contents of a DLL file may cause errors in the program that references the file. Therefore, DLL files should not be opened or edited.
