dll installation file. How to install DLL files on Windows

If a .dll library is missing or corrupted on your computer, its associated program or service will not function correctly. Windows will give an error that the DLL file is corrupted or missing. To solve the problem, you need to download the required library for your version of Windows, copy it to the desired folder and register it in the system.

Regardless of what program and what the dll-file is used for, the installation and registration of the library will always follow the same algorithm. All versions of Windows OS are guided by the same rules when connecting and registering dynamic libraries.

Step-by-step instruction:

How and where to copy the DLL file

DLL errors occur for various reasons: the file is corrupted, incompatible with Windows or a specific program, infected with viruses, or deleted. The solution is always the same: download the correct and complete version of the library, and then register the file in the system via the command line. Usually, the whole process takes no more than 2-5 minutes.

You can put (unzip and copy) any dlls here, and the installed files will work:

• For Windows 95/98/Me- the file is copied to the folder C:\Windows\System
• For Windows NT/2000- the file is copied to the folder C:\WINNT\System32
• For Windows XP, Vista, 7, 8- copy to folder C:\Windows\System32
• For 64-bit Windows- copy dll file to folder C:\Windows\SysWOW64

Where can I download the required library:

• If it is a game or program: with a different build of the game, from another PC where the application is running, from a disk (reinstall the program).
• If this is a system library, check the relevance of drivers, DirectX or another component, if the system writes in which file or program an error was made. You can copy a dll from another computer with the same bit depth and version of Windows (7, 8, 10). The error can be caused not by the library itself, but also by the program that uses it.
• You can always download the desired version of the file from dll archives like dll.ru or ru.dll-files.com . Carefully check which version of the OS the library is intended for. You should also carefully watch what is being downloaded: instead of the required library, many sites try to slip their paid software to fix errors with the DLL.
• Try to find an article with a solution to problems about the desired file in the section, or use the search on the site.

It is possible that the game or software is incompatible with the version of Windows, the solution may be to run in compatibility mode. If files are blocked by antivirus, you should take a closer look at the security of the application or add files to antivirus exclusions.

All changes will take effect after registering the library in the system and restarting the computer. Until then, it is useless to try to run anything - the system will not connect to the file.

To check the bitness of the system, right-click on the icon "My computer" and select item "Properties". In the folder that opens, in the System section, it will say: "System type: 64-bit operating system, x64 processor."

Registering a Library on Windows

The easiest way to register a DLL in Windows is through the command line or the Run window. To open a command prompt, you need to: click Start -> Run or a key combination Win+R, enter cmd.exe and press Enter. You can enter a command directly into this field without opening a command prompt.

To register the library, you need to write the command regsvr32 filename.dll and press Enter. For example, regsvr32.exe msvcp110.dll.

In order for the changes to take effect and the library to start working, you must to restart a computer. If Windows does not want to find the required file, you can specify the full path: regsvr32.exe full_path_to_file.dll, for example regsvr32.exe C:/Windows/System32/msvcp110.dll.

It often happens that some program does not want to start, because. You are missing a certain DLL file on your computer. What to do in this case? You need to download and install this file. There are usually no problems with downloading a DLL file from the Internet, but how to install it?

The first way is how to install the DLL file:
The easiest way is to simply place the dll file you downloaded into the folder with the program you are trying to run. This method is very simple, but does not always work.

The second way is how to install the DLL file:
The second way is to place the downloaded dll file in the system folders of your operating system. First you need to find out what operating system you have. To do this, right-click on the "My Computer" icon on the desktop and go to "Properties". The type of your operating system will be indicated there:

If you have a 32-bit operating system, then:

• Open "My Computer".
• Navigate to the "Windows" folder.
• Find the "System32" folder there and place the downloaded DLL file in it.

If you have a 64-bit operating system, then:

• Open "My Computer".
• Open the system drive (usually drive "C").
• Navigate to the "Windows" folder.
• Find the "SysWOW64" folder there and place the downloaded DLL file into it.
• Restart your computer for the changes to take effect.

The third way how to install a DLL file:
The third method is used if you installed the dll file in the second way, but you still get an error. You need to manually tell the system that you installed the dll file. For this:

• Go to the start menu.
• Enter "cmd" in the search bar. And open the found program.
• In the window that opens, enter " regsvr32 dll_name.dll". (for example, like this: "regsvr32 test.dll")
• Restart your computer.

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

How to open a DLL file

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

DLL files contain link settings to various resources used by the program, such as icons. DLLs are exclusively for Windows OS. On other operating systems, such files can only be opened using emulators (cross-platform applications for Mac OS are an exception). 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 files, as they are intended exclusively for developers. Editing this file may adversely 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 to open DLL files

View source code

One of the most common ways to view the 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 the correct display of the code for all files.

Alternatively, the dotPeek decompiler can be used. It is also free, but it can only work with programs written in C#.

Customizing the program interface

For this purpose, it is best suited. 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 there may be problems with large files (about 1 GB or more).

Debugging

The easiest way is to use Microsoft's Visual Studio. This is a fairly functional tool, whose capabilities include debugging a program, but it will only help if there is no protection on the file.

If you just need to download a DLL instead of a broken file (or there is no Dll), then DLL-helper will help here - a completely free program.

Dynamic web pages

There is another DLL format - files that generate code for sites. Such libraries can be opened in any convenient development environment, for example, visual studio. The browser will help to test them in action. It is better to use the latest versions of popular browsers, otherwise the file may not display correctly.

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

Web pages in DLL extension files are most often stored on Microsoft IIS web servers. The DLL extension must map to the appropriate server scripting engine in order to process the page correctly.

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

Many DLL files (read DLL) are provided by the Windows operating system, others are included with Windows programs. They also provide various software functions such as connection with external devices and hard disk input and output. They can also be referenced by cross-platform Mac apps.

Note: Removing or modifying 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.

A DLL file is a dynamic-link library component whose elements are used by almost all programs. The DLL is located in the root folder of the system. All components must be available, digitally signed, work properly and be up-to-date. 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, corrupted or outdated.

How to install a DLL file

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

Placing and registering library files

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

Let's determine what bit depth 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 bits. In our case, the Windows 10 64-bit operating system is installed.

·

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

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

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

Step 4 The file must be registered in the system.

You can do this by opening the command line with the combination "Win" + "R", or by clicking "Start" and "Run";

in the window that opens, enter the following, separated by a space: regsvr32 filename.dll – where, “regsvr32” is the command for registration, and “filename.dll” is the full name of the 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: "Unable 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 just to copy them to the System32 or SysWOW64 directory or place them in the root of the problematic game or program
3. Files have already been registered before

The second registration method

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

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

Step 3 A message will appear that "Everything went well", and just restart the computer

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

Here are some tips that you might find useful.

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

DLL suite program.

Before proceeding to the review of a new useful program, I want to thank my readers for their active support. My new book comes out on Monday. "Safe Freebie @ on the Internet". Recently, at the link I gave detailed information about the content of the new book and how to purchase it. Honestly, I did not expect such a hype. Of course, I understood that the book was relevant, but to such an extent ... Since then, after the announcement, pre-orders have arrived, almost half of the first print run! This makes me happy! So there will be a second and third additional editions. For those who are not yet in the subject, what the book is about and how it can be purchased, the link above.

After this lyrical digression, we smoothly move on to an overview of a new interesting program called DLL Suite. This program allows you to automatically find problems in dynamic libraries and fix them.

What are dynamic libraries? I will not load you with unnecessary information (do you need it?). Those who are interested can read information about them on Wikipedia at the link. I'll just say that they are necessary for the operation of a particular program or game you have installed. You have probably already encountered a periodically appearing window when starting some games or programs, “telling” that it is impossible to start the program or game due to the lack of one or another dynamic library (DLL). To fix this problem (download and install the necessary DLL), sometimes you need to "shovel" the entire Internet. The DLL Suite program, when launched, will automatically detect the missing dynamic libraries, download them and install them. The version of the program offered in this article is free. The paid version, extended and solves more problems, you can easily find it on torrents if you wish. We download the free version of DLL Suite from the official site at the link.

We install.

Let's get to work.

After system scan, DLL problems will be shown. We eliminate them and, if there is a desire, download the “cracked” paid version of the program from torrents and fix the remaining problems.
