REGSVR32 - Register or unregister a DLL in the Windows registry. Registering a DLL file in Windows Regsvr32 remove registration

We continue a series of articles in which we get to know and study the processes built into Windows 10. From time to time, these processes attract the attention of users with an increased load on the processor or memory of your computer, or the user’s simple curiosity makes him go to his preferred search engine and “google” what this or that process is responsible for. In this article you will find details about regsvr32.exe or "Server Microsoft registration».

Regsvr32.exe - what is it?

It should immediately be noted that regsvr32.exe, he is " Microsoft Registration Server" is a system component operating system. It is used to register Windows Components programs (DLLs and ActiveX objects) or remove them if necessary. By default, regsvr32.exe is not enabled. It is initiated only at the right moment, which is determined by the operating system or the installers / uninstallers of applications on your computer.

Microsoft registration server regsvr32.exe loads CPU

It happens, yes. From time to time, each user is faced with the fact that some system process begins to act up and load the resources of your computer. Regsvr32.exe is no exception. If you feel a drop in performance, an increase in processor temperature and fan noise, then some process is loading your CPU more. It may be the Microsoft Registration Server.

Please note that you cannot remove the Microsoft Registration Server - this is a standard part of the operating system required for correct Windows work. You won't be able to remove it or disable it, but you can find the reason why regsvr32.exe is behaving inappropriately.

First of all, use the universal solution to all problems - reboot. Perhaps you are dealing with a banal bug that will disappear after Windows startup"from scratch". If the reboot did not help and the process further loads the computer's resources, then some application accesses the registration server to work with a DLL library or another component. A hang, system crash, or a simple bug can cause a call to fail, which in turn leads to a constant load.

It is because of this that you should not try to kill regsvr32.exe itself. It is not in itself to blame for the high loads. The reason is the application that is performing the call, so you need to find this program and try to solve the problems that have arisen in it.

Since there is little detail about all processes in the standard Task Manager, you will need to use the Process Explorer utility developed by Microsoft. It can be downloaded from the official Microsoft website.

When you have identified the source of the problem, you need to look for ways to solve it. We can offer several different options. Not the fact that all of them will help. Windows is a complex thing and sometimes problems arise, the source of which can be very difficult to find. In many cases, these tips have helped fix the heavy load of the regsvr32.exe process, so try all of the options listed.

Microsoft Registration Server Program Stopped Error

Sometimes users encounter the above error directly related to regsvr32.exe. Again, the problem is not in the registration server itself, but in some application that conflicts with this system component. If you encounter this problem try the following:

How to disable or remove regsvr32.exe

This may be exactly what you are looking for, but before attempting to remove or disable this component, we want to assure you that you should not do this. The Microsoft Registration Service is just a tool that is used to register libraries. Disabling it (if it is possible in principle) will not solve the problem and will rather lead to even more problems. Instead of trying to disable regsvr32.exe, try to find the source of the error or abnormal high CPU usage as mentioned in the instructions above.

Sometimes when you try to start a game or application on your computer, you get an error that this 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 just 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 as well. So let's get started.

The first way to register a DLL

Before starting registration, it is worth making a remark and saying that there are only three ways, but each of them is almost the same as the others, so we advise you to read the article to the end, and then which method to use. Well, now let's go directly to how to register a DLL.

Initially, it should be said that all manipulations with registering a DLL file should be carried out only if this same 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 on the Internet. It is quite simple, so the user should not cause problems.

You need to get to the "Run" window. It can be opened in several ways. In the "Start" menu, go along the path "All Programs → Accessories" and select "Run" there. You can also search with the name of the utility in the same Start menu. But the easiest way is to press the Win + R keys.
When the window is open, in the input field you need to write the command "regsvr32.exe", then specify the path to the file to be registered.
It remains only to press 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 pressing the "OK" button, there are two options for the development of events. The first implies success, in which case you will be shown an appropriate message. Or failure, the corresponding window will fly out.

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

The second way to register a DLL

The second method is practically no different, only 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 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 way, how to register a DLL, is practically no different from the first, which was 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 is likely to be easier for the average user, so let's start considering it.

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

Right-click on the desired DLL file.
Select "Open With..." from the menu.
In the window, find and click the "Browse" button.
Path the path to the regsvr32.exe file, it is located in the System32 folder, which is located in the Windows folder on drive C.
Click "Open".

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

A message appears that the *. dll(For example, VCompLib.dll). In this case, the program, of course, does not start.

Error messages can be different (this depends mainly on the language in which the program is written), for example: "Component "MSCOMM32.OCX" not correctly registered: file is missing or invalid" , or "The application failed to start because MSVBVM50.DLL was not found. Reinstalling the application may fix this issue", or "Runtime DLL/OCX File error". This may bring up a window Program Compatibility Assistant with a message This program requires a missing Windows component.

Ways to solve the problem

If you encounter errors related to *. dll, necessary:

1. Reinstall the program.

2. If reinstalling the program does not help, you need to check the presence of the required files in the system.

Files *. dll, as a rule, should be located in the folder \Windows\System32(less often - in the directory of a specific program). If the files are present, you need to check them in.

If the required files are not there, search for them on the Internet, download and copy to a folder \Windows\System32 and to the program directory. Now we need to register them.

How to register *.dll files

Registering *. dll performed using the registration server regsvr32.exe(whose disk address is \Windows\System32).

Consider registration methods:

1. Press the button Start;

- in the text field Find programs and files enter regsvr32 filename–> Enter .

2. Press the button Start;

- in the text field Find programs and files enter cmd;

- in the list that appears (under the heading Programs) click right click cmd.exe;

- from context menu select Run as administrator;

– enter the password if prompted;

- in the opened window at the system prompt, enter regsvr32 filename , click Enter.

3. If you are using file manager Total Commander , you can register *. dll using the command line Total Commander.

If registering *. dll successful, a window will appear RegSvr32 with the corresponding message, for example: "Successful execution of DllRegisterServer in C:\WINDOWS\system32\msvbvm50.dll":

Notes

1. When registering *. dll they are recorded in Windows Registry. However, in the thread the corresponding parameter is created REG_DWORD with meaning 1 .

2. Using the command regsvr32:

regsvr32 ] dll file

/u- cancel registration DLL;

/s– “silent” 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;

Recently, many Windows users On 10/8/7, they began to observe an increased load on the processor and disk due to the Regsvr32.exe service, aka “Microsoft Registration Server”. The anomaly is easy to track through the standard "Task Manager". In the article, we will describe in detail what Regsvr32 is, why it calls high load on the system and how to disable the problematic process.

What is this process?

Microsoft Registration Server is system utility, which is activated when installing or removing various DLLs in Windows. These libraries can belong to both third-party software and games, as well as scheduled system updates. In normal mode, the background work of the Regsvr32.exe process is almost invisible. However, after recent OS updates, which the developers screwed up again, the registration server shows high loading CPU and Disk. Moreover, the load rises not only at the time of third-party installations, but also during PC downtime.

How exactly does Regsvr32.exe load the processor?

If we talk about the source of the anomalous load, then it can be any DLL file that has “frozen” and cannot be loaded in the system. Most often, the problem is in background programs that are registered in startup, or failed security updates.

It is worth noting that the Regsvr32.exe process itself has failed in Windows (7, 8 or 10) before, but the problem has become widespread since the beginning of 2018. This is most likely due to the fact that Microsoft began to carefully monitor computers with outdated security updates and install them on a voluntary/compulsory basis. In the last article, we talked about the automatic download of the program, which activates the update to version 1709.

How to turn off the registration server load?

If we talk about deletion, then it’s impossible to simply erase the regsvr32.exe service from the system, yet this is a system option. But you can try to find the source of the problem and disable it. Here's what to do right away:

Determine the source of the Regsvr32.exe crash

If all the half-measures described above do not help, then you need to use specialized software to detect problematic files. To do this, you can do the following:

After finding the source, turn to searching the Internet. Perhaps the program requires additional drivers, or there is its official version.

Conclusion

That's all - now you know what the “Microsoft Registration Server” service means and for what reasons it can load the processor. Finally, I want to note that in especially neglected cases, instead of regsvr32.exe can be activated by a virus, so check its location through the same Manager. If you get NOT to the address C:\Windows\System32, then delete it and run the computer through anti-virus scanners (AdwCleaner, MalwareBytes, Dr.Web).

Installing a game or a heavy application involves the automatic installation and registration of the necessary DLLs in the windows operating system. DLLs are dynamic libraries that can be repeatedly accessed by several applications. If an error occurs when a game or program tries to access a specific DLL, the user will see the message "dllregisterserver entry point not found" or "cannot start, missing .dll file." These and other errors reporting problems when accessing dynamic library, can be eliminated if you register yourself desired file dll in windows.

Why does an error occur when accessing a DLL

DLLs are added to the operating system when windows update and when installing applications. Based on this, the following main reasons can be distinguished why an error occurs reporting the absence or problems with the DLL file:

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

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

How to register a DLL in windows

If for some reason windows does not have a DLL required to run games and applications, the user can register it himself. This can be done in two ways, after downloading the necessary DLL.

Registering a DLL Using the Command Line

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

Run command prompt as administrator;
In the window that opens, write 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
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 the DLL cannot be registered

It is possible that windows will give an error to the library registration command, which indicates that the module is loaded, but the DllRegisterserver entry point was not found. There may be other variations of similar errors that cause a DLL to fail to register. These errors occur for the following reasons:

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

If errors occur when trying to register a DLL, the first step is to try downloading the official component from the vendor to rule out the possibility of a "dummy" file. For this you need to use 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 located in the same folder as the component or application's executable.exe file. 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 turned on, an error occurs “The program cannot be launched because the required DLL is not in the system.” Despite the fact that the windows family usually register libraries in the background, after you download and place your DLL file in the appropriate place, 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.

Solutions to the problem

There are several methods to eliminate this problem. Let's consider 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

For this you will need:

Click on the menu item "Register OCX/DLL".
Select the type of file you want to register.
Use the Browse button to specify the location of the DLL.
Press the "Register" button and the program will register the file itself.

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

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

Method 2: Run menu

You can register a DLL using the "Run" command in the start menu of the operating system. windows systems. 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:

Select the "Run" command from the "Start" menu.
Enter in the opened input field cmd.
Press "Enter".

You will see a window 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 to paste 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 installed version 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, the occurrence of an error can be caused by the fact that the file is already registered by the system. There are sites that distribute files that are not really 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 - it's just different methods launching the registration command - as it is more convenient for anyone.

We are glad we were able to help you resolve the issue.

How to register a DLL: three ways

Sometimes when you try to start a game or application on your computer, you get an error that this 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 just talk about how to register a DLL in windows 7. We will focus on the seventh windows version, but it is quite possible that the DLL will be registered on other versions as well. So let's get started.

The first way to register a DLL

Before starting registration, you should make a remark and say that there are only three ways, but each of them is almost the same as 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 go directly to how to register a DLL.

Click "Open".

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

Registering the DLL. What and how to do?

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

* In which directory to copy the libraries depends on the bitness 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 to the system directory. Everything should go well and you will see this message.

If you see this message

Then select a different bit depth and try to register again. Everything must be successful.

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

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

Registering a DLL in windows

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

To tell the truth, registering a library is quite simple - it only takes one step. However, you must have administrator rights to do this.

But there are some nuances in this. For example, in the case of successful registration of a DLL, the error of the absence of the required library 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 report that the DLLRegisterServer access point was not found. This does not indicate that incorrect actions were performed.

Three Methods to Register a DLL in the OS All of the steps below assume that a place to copy the library has been found and the DLL is located in the System32 or SysWOW64 directory or wherever it should be.

All DLL registration manipulations 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, while 64-bit is 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 register regsvr32.exe path_to_file_dll and click OK. In addition, "Run" can be found in the "Start" menu, if it is activated.

Then, upon successful completion, a notification should appear on the screen 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 the 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" for this you need to press Win + X, and then specify the required item. In the "seven" command line can be found in the "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. It is required to right-click on the DLL to be registered and select "Open with". After that, click "Browse" and find regsvr32.exe in the System32 or SysWow64 directories, and use it to run the DLL.
