Where is the dll located in windows 7. Registering the DLL

When trying to launch a game or application, we may encounter errors like “dllregisterserver entry point not found” or “application cannot be launched, dll file is missing.” There may be several such variations, but the essence is the same: the necessary libraries are not available at all or they are not registered. So, let's figure out how to use the library in the operating system and what to do if the problem is not resolved.

Description of the error

During the installation of Windows and other third-party programs, libraries are unpacked into system folders - .dll files, which are the execution environment for program code for applications. Without going into too much detail, this is how programs and games work. And in cases where the system does not see these files, errors occur.

Causes

This problem can be caused by a number of events:

  1. Virus infection. Unwanted software can damage and remove libraries from your computer. To do this, you should check your machine for viruses and remove them from your hard drive.
  2. Installer error. Typically, the software vendor adds all the necessary system files in the installation package for the application to run. But sometimes developers forget about this. Bottom line - if the computer does not have the appropriate resources (that are installed with another application), your program will not run. It’s much more offensive if you paid a hefty sum for this software.

    Attention! In some cases, the installation program itself warns you about the need to download additional content for the application to work. For example, for some games it is suggested to install the latest version of DirectX separately.

  3. System error. Due to various circumstances that are not always in our control, Windows may lose track of some .dll files. The reason for this is careless manipulation of registry entries.

Methods for registering libraries

There are two ways to add .dll files to the system registry.

Using the command line

To do this you will need to do the following:


Using the Run window

Two-click method:


Why can't I register .dll and how to fix it?

There are three reasons why system file registration fails:

  1. The library is already registered. In this case, the reason is the file itself, which is damaged or infected with a virus.
  2. Registration is not possible. The .dll file may simply be a dummy file or may be incompatible with the version and components of the operating system.

    Attention! Never download .dll files from file hosting services and other suspicious sites. Download libraries only from official sources!

  3. There is no registration function. Some libraries are not designed for registration and simply do not have this function.

There are three ways to get out of this situation:

  1. Download the official system component from the supplier's resource. For example, for the xlive.dll file, you need to download and install the Microsoft Games for Windows package, which can be downloaded from the Microsoft website.

    Advice! If such a situation occurs, look for where to download the system component (this will be a genuine site), and not a separate file.

  2. In case you are a developer and have created your own library, register it using regasm.exe.
  3. Sometimes, to use the .dll file, you need to move it to the application folder - to the directory where the .exe executable file is stored.

So, we have looked at a number of ways to register libraries in the system and eliminate the “dllregisterserver entry point not found” error. There should be enough of them. But if you have a unique situation or know another way to solve the problem, please share it in the comments.

File DLL is a functional module that can be used by multiple programs as long as it is registered.

Operating systems typically register DLLs in the background, but sometimes due to hard drive corruption, a software installation error, or a computer virus infection, you may need to register the DLL file manually.

This instruction will tell you how to perform this procedure.

Method 1
  • Click Start
  • In the "Search programs and files" text box, enter:
    regsvr32 [full_file_name]
    If there are spaces in the path, the full file name must be written in quotes.

    For example: regsvr32 "C:\Program Files (x86)\1cv77\BIN\v7plus.dll"

  • Press Enter

Method 2
Notes
  1. When registering *.dll files, they are written to the Windows Registry. At the same time in the thread a corresponding REG_DWORD parameter is created with a value of 1.
  2. Using the regsvr32 command:
    regsvr32 ] DLL file
    /u    – unregisters a DLL
    /s– “quiet” mode – message windows are not displayed
    /i– calls DllInstall, passing an optional command_string as a parameter; when used with the /u switch, calls DLLUnInstall
    /n– does not call DllRegisterServer. Can be used with the /i switch.

Check out how this method works. To register a DLL file, you can use the "regsvr" command and the name of the DLL file (if the file supports this command). This will create a path from the Windows registry to the DLL file, making it easier for the system to find and use the file.

  • Typically, this method is used to register DLL files that belong to third-party programs and that directly interact with system utilities (for example, the command line).

Understand the essence of the “entry point” error. If the DLL file is already registered, it does not support the "regsvr" command, or its code does not allow you to connect to the Windows Registry, you will receive the error message "The module was loaded but the entry point DllRegisterServer was not found." loaded, but DllRegisterServer entry point not found). If this message appears on your screen, you will not be able to register the DLL file.

  • The "entry point" error is not so much a problem as it is a confirmation that the DLL file does not need to be registered.

  • Find the DLL file you want to register. Go to the folder with the desired DLL file and find it.

    • If the DLL file is for an installed program, open the program's folder (for example, C:\Program Files\[program name]).

  • Open the properties of the DLL file. Right-click on the DLL file and select Properties from the menu. A pop-up window will open.

    Find the DLL file name. In the text box at the top of the Properties window you will find the full name of the file.

    • Most DLL files have complex names, so leave the Properties window open to copy the name later.

  • Copy the path to the DLL file. Hold down the left mouse button and drag along the text that appears in the Location row, and then press Ctrl + C to copy the path to the DLL file.

    Find the command line. Type command prompt in the Start menu search bar. The Command Prompt icon will appear at the top of the Start menu.

    Open Command Prompt as Administrator. For this:

  • Go to the directory with the DLL file. Type cd , press the spacebar, press Ctrl + V to paste the path to the DLL file, and then press ↵Enter.

    • For example, if the DLL file is in the "SysWOW64" folder, which is located in the "Windows" folder, the command would look like this: cd C:\Windows\SysWOW64

  • Enter the command "regsvr" and the name of the DLL file. Type regsvr32 , press the spacebar, enter the name of the DLL file (along with the .dll extension) and press ↵Enter. If the DLL file can be registered, a registration confirmation will appear on the screen.

    • For example, if the DLL file name is "usbperf.dll", the command would look like this: regsvr32 usbperf.dll
    • To copy the name of a DLL file, reopen the folder containing the DLL file (the Properties window opens), highlight the file name, and press Ctrl + C. Then paste the name into the command line - to do this, press Ctrl + V.
    • If the DLL file is already registered or cannot be registered, an "entry point" error will be displayed rather than a registration confirmation.

    • 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 the command line with the combination “Win” + “R”, or clicking “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 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: "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 “Do not show hidden folders” in the 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.

    Installing a game or heavy application involves automatic installation and registration of the necessary DLLs in the Windows operating system. DLLs are dynamic libraries that can be accessed multiple times by multiple applications. If an error occurs when a game or program attempts to access a specific DLL, the user will see the message “dllregisterserver entry point not found” or “cannot launch, missing .dll file.” These and other errors that indicate problems when accessing a dynamic library can be eliminated if you independently register the required DLL file in Windows.

    Why does an error occur when accessing a DLL?

    DLLs are added to the operating system when Windows is updated and when applications are installed. Based on this, we can identify the following main reasons why an error occurs indicating a missing or problem with the DLL file:

    • The DLL was not installed. There may be two reasons for this - Windows is not updated to the current version, and the library comes with one of the latest updates, or the game/application during installation for some reason did not install and register new DLLs. Please note: Most often, application installation files include all the necessary DLLs, and the developers do not hope that the necessary components have already been installed on the computer.
    • Damage to DLLs. This problem most often occurs if DLLs were damaged by virus software or careless user actions, for example, making changes to the registry that led to damage to dynamic libraries.

    Most DLLs are installed on the computer along with DirectX, so if, when installing a game or application, you are prompted to update/install DirectX, you do not need to refuse it, otherwise there is a high risk of the error “cannot be launched, the .dll file is missing.”

    How to register a DLL in windows

    If for some reason Windows does not have a DLL library necessary to run games and applications, the user can register it independently. This can be done in two ways, by first downloading the necessary DLL onto the computer.

    Registering DLLs Using the Command Line

    To register a DLL existing on your computer via the command line, do the following:

    1. Run Command Prompt as Administrator;
    2. In the window that opens, enter the command: regsvr32.exe path_to_DLL_library

      Instead of “path_to_DLL_library” write the full path to the library, for example: C:/windows/system32/comctl32.dll

    3. Press Enter and the DLL will be registered.

    Registering a DLL Using the Run Line

    Registering a DLL through the “Run” line is practically no different from actions with the command line. The user needs:


    What to do if you can't register a DLL

    It is possible that Windows will generate an error when responding to the library registration command, indicating that the module is loaded, but the DllRegisterserver entry point was not found. There are likely other variations of similar errors that prevent the DLL from being registered. Such errors occur for the following reasons:

    • Some DLLs are not designed to be registered and do not have this feature;
    • The library is already registered by the system. If errors occur when accessing it, it is most likely infected with a virus or damaged;
    • Invalid DLL file. There may be situations when DLL files are initially damaged or do not contain the necessary components;
    • The DLL is not compatible with the current version of Windows.

    If you encounter errors when trying to register a DLL, the first step is to try downloading the official component from the vendor to eliminate the possibility of a dummy file. To do this, you will need to use a search engine and find which system component the problematic DLL belongs to.

    In rare situations, problems with registering a DLL may occur if it is not in the same folder as the component or application's executable file.exe. In this case, you need to move the library to the folder with the executable file and try to register it again.

    Registering the DLL file in Windows OS

    After installing various programs or games, you may encounter a situation where, when you turn it on, the error “The program cannot be launched because the required DLL is not in the system” appears. Despite the fact that Windows operating systems usually register libraries in the background, after you download and place your DLL file in the appropriate location, the error still occurs and the system simply “does not see” it. To fix this, you need to register the library. How this can be done will be discussed later in this article.

    Options for solving the problem

    There are several methods to resolve this problem. Let's look at each of them in more detail.

    Method 1: OCX/DLL Manager

    OCX/DLL Manager is a small program that can help you register a library or OCX file.

    Download OCX/DLL Manager

    To do this you will need:

    1. Click on the menu item “Register OCX/DLL”.
    2. Select the file type that you will register.
    3. Using the “Browse” button, specify the location of the DLL.
    4. Click on the “Register” button and the program will register the file itself.

    OCX/DLL Manager can also unregister a library; to do this, you will need to select the “Unregister OCX/DLL” item in the menu and then perform all the same operations as in the first case. You may need the undo function to compare results when a file is activated and when it is disabled, as well as during the process of removing some computer viruses.

    During the registration process, the system may give you an error indicating that administrator rights are required. In this case, you need to launch the program by right-clicking on it and selecting “Run as administrator.”

    Method 2: Run Menu

    You can register the DLL using the Run command in the start menu of the Windows operating system. To do this you will need to do the following:


    Method 3: Command Line

    Registering a file via the command line is not much different from the second option:

    1. Select Run from the Start menu.
    2. Enter cmd in the field that opens.
    3. Press "Enter".

    A window will appear in front of you in which you will need to enter the same commands as in the second option.

    It should be noted that the command line window has a function for pasting copied text (for convenience). You can find this menu by right-clicking on the icon in the upper left corner.

    Method 4: Open with


    Possible mistakes

    "The file is not compatible with the installed version of windows" - this means that you are most likely trying to register a 64-bit DLL on a 32-bit system or vice versa. Use the appropriate command described in the second method.

    "Entry point not found" - Not all DLLs can be registered, some of them simply do not support the DllRegisterServer command. Also, an error may occur because the file is already registered by the system. There are sites that distribute files that are not actually libraries. In this case, of course, nothing will be registered.

    In conclusion, it must be said that the essence of all the proposed options is the same - these are just different methods for launching the registration command - whichever is more convenient for you.

    We are glad that we were able to help you solve the problem.

    How to register a DLL: three ways

    Sometimes when you try to launch a game or application on your computer, you get an error that the DLL file was not found. The fact is that this file may be on your computer, but it is simply not registered. In this article we will talk about how to register a DLL in Windows 7. We will focus on the seventh version of Windows, but it is quite possible that the DLL will be registered on other versions. So let's get started.

    First way to register a DLL

    Before starting registration, it’s worth making a note and saying that there are only three methods, but each of them is almost identical to the others, so we advise you to read the article to the end, and then make a choice which method to use. Well, now let's move directly to how to register a DLL.

    Initially, it is worth saying that all manipulations with registering a DLL file should be carried out only if this very file is located where it should be. Most often this is the system32 folder. In the example, we will represent this folder.

    Now let's talk about the most common way to register a DLL, at least it is the most common way on the Internet. It is quite simple, so it should not cause problems for the user.

    1. You need to get to the "Run" window. It can be opened in several ways. In the "Start" menu, follow the path "All Programs → Accessories" and select "Run" there. You can also search for the name of the utility in the same Start menu. But the easiest way is to press the Win+R keys.
    2. When the window is open, you need to enter the command “regsvr32.exe” in the input field, then specify the path to the file that needs to be registered.
    3. All that remains is to click the “OK” button.

    Please note that the path to the file must be specified in full. Starting from drive C. For example: regsvr32.exe c: windows /system32/openal32.dll.

    In this case, after clicking the "OK" button, there are two options for the development of events. The first one implies success, in which case you will be shown a corresponding message. Or failure, the corresponding window will pop up.

    This was the first way to register a DLL, but we remind you that there are only three of them, so we move on.

    Second way to register DLL

    The second method is practically no different, only in the place of action. You need to get into the “Command Line” utility; you can also do this in several ways: either in the “Start” menu in the standard folder, open the program of the same name, or by calling the “Run” window, enter the “cmd” command. It's up to you to decide.

    Now the command line is open in front of you, in it you need to enter exactly the same data that was entered in the first method. That is, initially specify the program that will work with the dll (regsvr32.exe), and then the path to the file.

    As you can see, the second method of registering a DLL is practically no different from the first, as discussed at the beginning of the article. But the third one has more noticeable differences, so let’s move on to it.

    The third way to register a DLL

    This method will most likely be simpler for the average user, so let’s start looking at it.

    All you need to do is open the DLL file using regsvr32.exe. Here's how to do it:

    1. Right-click on the desired DLL file.
    2. From the menu, select "Open with...".
    3. In the window, find and click the "Browse" button.
    4. Find the path to the regsvr32.exe file, it is located in the System32 folder, which is located in the windows folder on drive C.
    5. Click "Open".

    That's all, now you know three ways of what to do when a DLL error appears.

    Registering a DLL. What and how to do?

    1. Copy the downloaded library to the desired system directory. (this is either system32 or SysWOW64)*

    * Which directory to copy libraries to depends on the bit depth of the application. If you don't know exactly which folder to copy to, copy to both J

    2. Download the archive at the bottom of the post, unzip it, run the reg.bat file with administrator rights, select the bit depth you need, press Enter and paste the name of the library that you copied into the system directory. Everything should go well and you will see this message.

    If you see such a message

    Then select a different bit size and try to register again. Everything should go well.

    P.S. If you need to register a library that is located in a different directory (not the system directory), then you must specify the full path to the library in the library name.

    For example C:\Program Files\1Cv77\BIN\V7PLUS.dll

    Registering DLLs in Windows

    Very often, users have a question about how to register a DLL in the seventh or eighth version of Windows. Typically, this question appears after the system informs the user that the required library is missing on the PC.

    In truth, registering a library is quite simple - you only need to complete one step. However, you must have administrator rights to do this.

    But there are some nuances to this. For example, if the DLL registration is successful, the error that the required library is missing may not disappear. In addition, a RegSvr32 error may occur and a notification that the module is not able to work on a PC with this version of the operating system. It may also indicate that the DLLRegisterServer access point is not found. This does not indicate that incorrect actions were performed.

    Three methods to register a DLL in the OS All the steps described below assume that a place to copy the library has been found and the DLL is located in the System32 or SysWOW64 directory or in another place where it should be.

    All manipulations for DLL registration will be performed using regsvr32.exe, but here you need to pay attention that when using a 64-bit system, this file can be located in two directories: SysWOW64 and System32. It is worth noting that these files are different, with the 64-bit one located in the System32 directory. It is recommended in each case to write the path to regsvr32.exe, and not just the file name.

    The first method is quite common and can often be found on the Internet. It consists of several manipulations. Initially, you need to press Win + R, and then in the “Run” window you should enter regsvr32.exe path_to_dll_file and click OK. In addition, “Run” can be found in the “Start” menu if it is activated.

    Then, if successful, a notification should appear on the screen indicating that the library registration was successful. However, most likely, a notification will appear that the module has loaded, but the DllRegisterServer access point is missing and you need to make sure that the DLL is the right file.

    The next method involves running a command line as an administrator and writing the same command as in the above method. You need to open the command line. In the “eight”, to do this, you need to press Win + X, and then specify the required item. In the “seven”, the command line can be found in “Start”. You need to right-click on it and select “Run as administrator”.

    Then you should enter regsvr32.exe path_to_dll, as in the previous method. However, registration will most likely fail.

    In addition, there is a method that will be needed in rare cases. You need to right-click on the DLL to be registered and select “Open with”. After this, you should click “Browse” and find regsvr32.exe in the System32 or SysWow64 directories and use it to run the DLL.
