DLL files are essential for every PC, but sometimes DLL files can go missing on Windows 10, and that can cause issues.
And if a certain important DLL file is missing from your computer, you probably won’t be able to run a desired program or app.
So, in this article, we’re going to show you what to do if a certain DLL file is missing from your computer.
To better understand the problem, let’s first say what a DLL file is. DLL is short for Dynamic Link Library, and it is a type of file that contains a set of instructions used by other programs to perform certain operations.
For example, programs use a DLL file to find the free space on a hard drive, locate a file in a particular directory, etc.
If a DLL file that is needed by a certain program is missing from your computer, you won’t be able to run that program, and you’ll receive an error message.
Let’s now see what to do if a DLL file is missing from your computer.
Why do DLL files go missing?
There are various reasons behind it, but usually, it’s a program on your computer overwriting a DLL file and rendering it unusable. And once this happens, other programs wouldn’t be able to fetch it and may, in turn, stop working.
Also, many times, uninstalling a program can lead to missing DLL files in Windows 10 if the particular program deletes the DLL files as well in the process.
Lastly, it could be malware or virus deleting the DLL files, and in this case, running a full-system scan using an effective antivirus should do the trick.
How do I fix missing DLL files in Windows 10?
1. Run a third-party DLL fixer
There are plenty of third-party programs out there that promise to fix or replace missing or broken DLLs, and most of them stay true to their word.
2. Run SFC Scanner
- Right-click on the Start Menu button, and choose Command Prompt (Admin).
- Enter the following command and press Enter:
- sfc/scannow
- Wait for the process to finish (it may take a while because it will scan your whole system for errors).
- Restart your computer.
- Check if your DLL is still missing.
SFC Scanner is Windows’ own tool for solving various system-related problems.
This tool can also be used to detect crucial missing DLL files on your computer, so that’s what we’re going to try first, in order to solve the missing DLL problem.
If SFC Scanner found the missing DLL file, you’re good to go, but in case this tool wasn’t helpful, try some of the solutions listed below.
If you’re having trouble accessing Command Prompt as an admin, then you better take a closer look at this guide.
3. Run DISM
- Run Administrative Command Prompt (as shown above).
- Enter the following command into the Command Prompt, and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
- Wait for the process to finish.
- Restart your computer.
This solution is similar to the first one, because DISM (Deployment Image & Servicing Management) tool is used when SFC Scanner fails to repair system files, in our case find the necessary DLL file.
If SFC Scanner didn’t solve the problem, DISM should. But even if this tool proves to be useless for your DLL problem, you’ll have to fix it manually.
4. Download a DLL file manually
So, if there’s no other way to solve the problem with a missing DLL, you can download it manually from the internet. But be aware that there are a lot of sites online offering free DLL files, but just a few of them are trustworthy.
I also have to mention that if you can run a third-party program or a game due to a missing DLL file, try to reinstall that program, and you’ll maybe reinstall the DLL file, as well.
If you don’t feel comfortable downloading missing dll files online, you can try to copy them from another working PC.
5. Install DirectX
If DLL files are missing from your PC, you might be able to fix the problem simply by installing DirectX. According to users, they are usually getting the error message about missing files when trying to start a certain video game.
To fix the problem, you just need to install the required version of DirectX and the issue should be resolved. You can download the necessary files from Microsoft’s website, but sometimes there’s a DirectX setup file on your game’s disc so you can install it from there.
If you’re getting error messages while trying to run certain games, you should be able to fix the problem by installing the necessary DirectX. If you want to find out more about the latest release of DirectX, check out this updated article.
6. Reinstall Visual C++ Redistributables
According to users, If DLL files are missing from your PC, you might be able to fix the problem simply by reinstalling Visual C++ Redistributables.
Many applications require these files in order to work, therefore you need to download them from Microsoft’s website. After installing the necessary Redistributables the issue should be resolved.
Keep in mind that certain applications require an older version of Redistributables in order to work, so you’ll might have to download and install the later versions as well.
Few users reported that they fixed this problem simply by reinstalling the previously installed version of Redistributables. After doing that, the issue was resolved completely.
7. Disable or remove your antivirus
According to users, sometimes your antivirus software can interfere with Visual C++ Redistributables and prevent you from installing the necessary DLL files.
To fix the issue, you need to disable your antivirus and check if that solves the problem. If disabling the antivirus doesn’t help, you might have to uninstall it.
The best way to do that is to download a dedicated removal tool and use it to remove all files associated with your antivirus.
If you’re a Norton user, we’ve got a dedicated guide for you to completely uninstall the antivirus. Also, there’s a similar one for McAfee users.
After removing the antivirus, try to install Visual C++ Redistributables. Many users reported problems with AVG, but this issue can also appear with other antivirus tools, so be sure to remove or disable it.
You don’t have to worry about malware after removing your antivirus. Windows Defender is as capable, and in some cases better, at protecting your PC against threats. Read this article to find out more.

How to install DLL files in Windows 10?
You don’t need to perform any special procedures to install a DLL file. However, there are a few ways to ensure its installation.
➡ Copy it in the same location as the executable file
In the large majority of applications, the DLL files are located in the same folder as the executable file (.exe) so copying or replacing the missing file there will do the trick.
If that’s not the case, check the missing DLL error you received and see its exact location and paste it in the same place.
➡ Paste the DLL in the dedicated Windows folder
If there is a missing DLL in Windows, you can paste the new DLL in the System32 (for 32 bit) or SysWOW64 (for 64 bit) Windows folders.
You will agree to replace the file if it already exists but make sure that the new DLL is right for your system (32 or 64 bit).
➡ Reinstall the malfunctioning app
Looking for a specific DLL file can be a bit tedious and time-consuming, but if the DLL is missing from an app, reinstalling it will also bring a fresh DLL with it. The same idea would work if the missing DLL files in Windows 10 were for games.
This is a great solution to install a corrupt DLL file such as the OneSettingsClient.dll, especially if the malfunctioning app is small because the whole process won’t take more than a few seconds and clicks.
That’s it for missing DLL files in Windows 10, I hope this article helped you to solve the problem. If you have any questions or suggestions, just write them down in the comments section below.
