DLL files are an important part of the Windows operating system. They help programs run properly and can be shared by multiple programs. However, sometimes DLL files can become corrupted or go missing. This can lead to errors when trying to run certain programs. Luckily, there are some easy ways to fix DLL files missing errors on Windows. In this blog, we’ll give you step-by-step instructions on how to do just that. Keep reading to learn more.

What is a DLL File?

What is a DLL File?

DLL files are actually dynamic link library files. They’re small files that contain code that can be used by multiple programs on your computer. This code can include functions, data, and even resources like images or icons. And since DLL files can be shared by multiple programs, they help keep your computer’s memory usage down. So, when a program on your computer is unable to start because a DLL file is missing, it’s usually because the DLL file has been deleted or misplaced somehow. 

How Do DLL Files Work?

Dynamic link library files contain code that is used by more than one program at a time. This code is loaded into memory when the program that uses it is run. The advantage of using a DLL file is that it can be used by multiple programs simultaneously, which reduces memory usage on your computer. Additionally, if a DLL file needs to be updated, you only need to update the file once and all programs that use it will have access to the updates. 

DLL files are different from regular executable files because they are not directly executed by Windows. Instead, they are called by other executable files. When an executable file calls a DLL file, an entry point is executed. This entry point is a function within the DLL file that tells Windows what needs to be done when the called program is run. After the entry point function has been executed, the control is returned to the original program so that it can continue running. 

What Causes Missing DLL File Errors?

There are a few different things that can cause DLL files missing errors. 

  • One of the most common is an outdated or corrupted driver. Drivers are pieces of software that help your computer talk to the hardware connected to it. 
  • If you have an outdated or corrupt driver, it can cause problems with how your computer communicates with the hardware, which can in turn cause errors.
  • Another common cause of missing DLL file errors is a virus or other malware infection. Malware can sometimes delete or corrupt important system files, which can lead to errors. 
  • Finally, another possible cause of missing DLL file errors is a change made to your Windows Registry. The Windows Registry is a database that stores information about your computer’s configuration. Sometimes, changes made to the Registry can cause problems that lead to errors like missing DLL files.

Why are DLL Files Important? 

DLL files play an important role in your system because they improve efficiency by allowing programs to share resources without duplicating files. Additionally, DLL files provide a way for developers to modularize code so that each module can be updated independently without affecting the entire program. This modular design makes it easier to develop and test programs because changes can be made to one module without affecting the other modules.

Moreover, DLL files make it possible for developers to create language-independent programs. This is because each language has its own set of DLL files that can be called from any language-specific program. 


So there you have it, a few easy ways to fix DLL files missing errors on Windows. Hopefully one of these methods worked for you and your computer is now running smoothly again. If not, keep in mind that there are plenty of other resources online where you can find help with this issue. And don’t forget, if all else fails, you can always take your computer to a professional to get it fixed. 

Frequently Asked Questions

Q1. How to fix missing DLL files in Windows?

There are a few ways to fix DLL files missing in Windows. One is to use the System File Checker tool which comes with Windows. This will scan your system for missing or corrupt files and replace them as necessary. Another option is to download the missing DLL file from a trusted website and place it in the correct location on your computer. 

Finally, you can use a dedicated DLL fixer tool to automatically find and replace missing or corrupt files. Whichever method you choose, be sure to back up your important files first in case something goes wrong.

Q2. Why do DLL files go missing?

DLL files go missing when they are deleted or moved from their original location. This can happen if the user accidentally deletes the file, or if a virus removes the file. Moving DLL files can also cause problems, as the operating system may be unable to find the file when it is needed. 

As a result, it is important to keep dll files in their original location and to make sure that they are not moved or deleted. If a dll file is missing, it can often be replaced by downloading it from the Internet or by using a software program that restores missing files.

Q3. Which program runs the DLL files?

DLL files are run by the Windows operating system. When a DLL file is called by an application, the operating system loads the file into memory and then runs the code within the file. This allows applications to share code, which can save both space and resources.

Q4. Can we open the DLL files with Notepad?

Yes, you can open DLL files with Notepad. However, doing so will not allow you to view the file’s contents in a readable format. DLL files are compiled binary files that are used by programs to perform specific tasks. Unlike text files, which can be opened and read by any text editor, DLL files can only be used by programs that are specifically designed to work with them.
