Sometimes it becomes necessary to reinstall dll libraries that play an important role in the functioning of individual applications or the system as a whole. They crash due to incorrect user actions, modification by viruses, or the removal of one program from a complex of applications using the same library. How to fix this error?
Library Search
The first step after an error message is to call the search menu through the Start button in Windows 7 or the magnifying glass icon in the ten and eight. In the first case, the line will already be on the main menu at the bottom in the left block. In the second case, it will be a separate drop-down menu. In the search bar you must enter the name of the library with the extension without specifying the path. For example, if the error refers to C://Users/Nastroyvse/video.dll, then you only need to write video.dll in the line. If successful, the new path to the specified file will be displayed in Explorer or directly in the search window. Then there are two possible ways. The first is to copy this file to the folder indicated by the error and restart the computer. When called, the program must see this library. If this does not happen or this library is not on your computer, you will have to register.

Your DLL has been successfully registered and can be used by Windows programs. Note that if you receive an error message, you may want to use the 64-bit version of the command rather than the 32-bit version. If you installed a 64-bit version of Windows and the DLL is a 32-bit version, you must run the command with the 32-bit version of regsvr32:
%SystemRoot%SysWoW64 regsvr32
Where to download libraries
The treasured DLL files can be obtained from various sources. It is advisable to look for them on the official website of the manufacturer or program. If the software version has been updated during operation, it is advisable to download it and reinstall it. The latest versions of libraries will be installed along with it. If the program’s website does not work or there are no updates, specialized websites with collections of these same dll files will come to the rescue. Just enter the name of the library in the search bar of the site, and you will receive a direct download link. Before carrying out registration actions, it is necessary to run the latest anti-virus databases. To do this, you need to right-click on the downloaded file and select the option to scan with an antivirus. If the file is clean, feel free to install it. Among the popular storages:
- https://ru.dll-files.com/;
- https://www.dll.ru/;
- https://dlltop.ru/.
When downloading files, pay attention to the bit depth and version of the operating system. You can find them in the My Computer menu in Windows 7 or in the Computer tab of Explorer in Windows 10. To access the information, right-click or touchpad. In the context menu that pops up, left-click on the item “About the system”. An incorrectly selected library will function with errors or stop running altogether.
Opening a file through a program
Finally, when considering how to install DLL files, you can generally take a roundabout route.
To perform the required operation, you first need to call up the context menu via RMB, select “Open with...”, and then use the browse button or search for programs on your computer to go to the System32 directory and specify the regsvr32.exe application.
Note: when using all three proposed options, after completing the registration of dynamic libraries, a complete reboot of the computer is mandatory, since without it the system still does not recognize the registered object after completing the procedure.
The installation location cannot be changed
After downloading the correct version, you need to install it in the system root folder. Its name depends on the bitness of the operating system. For 32-bit systems it is C:/Windows/System32, and for 64-bit systems it is C:/Windows/SysWOW64. Both folders may exist on the computer. Each of them has its own library registrar. When registering files, you need to open the correct one. There are 3 registration methods in total.
A few final words
It remains to give some practical advice on conducting registration processes. First of all, pay attention to the system capacity. The downloaded file must have the same bit depth. Accordingly, place the files in the above locations. Otherwise, registration will not produce results. If you need to set administrator rights to perform some operation, you must agree. If updates are available for downloaded libraries, download the most recent and current version of the file. This will save you from the appearance of various kinds of conflicts between installed programs and their additionally installed components. Finally, if the files you are looking for were nevertheless downloaded from a dubious resource, and they are copied to the system partition, for example, from a flash drive, first check them for viruses, using the standard commands of the antivirus itself built into the Explorer RMB menu.
Win+R
It consists of calling the registrar regsvr.exe using a combination of these keys. The “Run” line will open, where you need to enter the following command: regsvr32.exe path_to_dll_file. It is advisable to indicate the path to regsvr32 so as not to cause confusion.
IMPORTANT. 64-bit operating systems have two regsvr32.exe files - both System32 and SysWOW64. They are completely different, you need to take this into account. The 64-bit logger file is located in the System32 folder!
After clicking OK, the system will display a message indicating the result of processing the request.
alternatives
Saving the DLL file will not solve all the problems it creates. Sometimes the DLL file is not the cause of the problem, but only the way it manifests itself. The problem may be in the library itself or in the application. In this case, you should try to uninstall and reinstall the application, or uninstall and install the library that uses it.
It may also be useful to update the library if a newer version is available. Finally, make sure the library version is correct for the application. You can check the application requirements to determine which libraries or frameworks are required to run the application.
Reasons for refusal of registration
- Not all files from the Internet require registration. To do this, they must have a DLL Registration Server entry point.
- Also, the file may turn out to be a dummy and not a library.
But this can be fixed quite simply.
- Copyright libraries can be run through the regasm.exe program.
- When a registration error occurs, focus on finding information about the file itself rather than searching for the source. This increases the chances of downloading from the official website without any hassle.
How to resolve the error
Window.dll – just like other system files, is a standard DLL library. This file is used in the operation of the OS, and is also used in the operation of third-party programs. The name of this file is often confused with another name - Windows.dll. Despite the apparent similarity with the name of the OS itself, the library is not critical. When you have a missing system document or problems with it, you can still continue working, but with some restrictions. You have 3 options to resolve this error:
- Download and replace;
- Download the software containing the necessary data;
- Restore the system;
Of the entire list, we do not recommend system recovery. This option will definitely help you, but the problem is different. This is not such a significant error and problem that you need to restore the system from a restore point. Of course, if this is not the only problematic library, you should consider restoring or even reinstalling the OS.
You can download the library on this page. You will have to replace this file manually. You can find the path using search. Typically, the library is located in the System32 system folder. But the exact path may vary depending on your device. As a rule, this library does not disappear anywhere, problems or failures just begin with the file that is stored on your computer.
There is another option - reinstall/install the software, which includes the library you need. The package includes the following utilities:
- Microsoft Visual C++;
- Microsoft .NET Framework;
These are three programs that should be installed on your device without any problems in the file. If you don't have one of these programs, then you need to install them urgently. If the programs are there, but there are also problems, you need to reinstall one of these programs. Which one? You will learn as you go. It is enough to reinstall them one by one until you notice that your OS stops giving the Window.dll error.
Why does the dll error occur?

Rundll32 algorithm
In general, there is no revolution here, since rundll32 is a classic application that dynamically links DLL functions at runtime. In general terms, the rundll32 algorithm can be described as follows:
- The LoadLibrary function is called, which loads the selected DLL;
- The GetProcAddress function is called to obtain the address of the entry point of the function called from the library;
- Calls to check whether a function meets specific requirements;
- The function itself is called and input parameters are passed to it;
- The function exits upon completion of its work;
- The DLL is unloaded from process memory.
