Fix: DLL Files Missing from Your Windows 10 Computer
Although an average user isn’t so familiar with the work of DLL files, these files are essential for running almost every program in Windows 10, and all other versions of the operating system. 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.
What to do if a DLL File is Missing from Windows 10
Missing DLL files can cause many problems on your PC, and users reported the following issues:
- Sysmenu dll file missing – Many users reported that Sysmenu dll file was missing on their PC. This can be a big problem, but you should be able to fix the issue using SFC or DISM scan.
- Msvcr100.dll file missing error – This file is usually associated with Visual C++ Redistributables, and after installing the necessary components, the issue should be resolved.
- T8extpex.dll file is missing – T8extpex.dll is another file that can become missing, however you should be able to recover it using one of our solutions.
- Hal.dll files missing – Another problematic file is Hal.dll. If this file is missing, you won’t be able to run your favorite applications.
- DLL file missing for iTunes, SQL Developer – Many users reported that DLL files for their favorite applications are missing. This is a relatively common problem and you can fix it by reinstalling the problematic application.
- Kernel32.dll files missing – Several users reported that Kernel32.dll is missing on their PC. This is a system file but you should be able to restore it by repairing your Windows installation.
To better understand the problem, let’s first say what is a DLL file. DLL is short for Dynamic Link Library, and it is a type of file which 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 which 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.
Quick solution to fix missing .DLL files
- Step 1: Download this PC Scan & Repair tool (it will replace your missing/damaged DLL files with fresh, clean and up-to-date ones)
- Step 2: Click “Start Scan” to find Windows issues that could be causing errors with missing .dll files in Windows 10
- Step 3: Click “Start Repair” to fix all issues.
Solution 1 – Run SFC Scanner
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. Here’s how to run SFC Scanner in Windows 10:
- Right-click on the Start Menu button, and choose Command Prompt (Admin).
- Enter the following command and press Enter:
- 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.
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.
Solution 2 – Run DISM
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. To run DISM, do the following:
- Run Administrative Command Prompt (as shown above).
- Enter the following command into the Command Prompt, and press Enter:
- Wait for the process to finish.
- Restart your computer.
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.
Solution 3 – 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 trustful. 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.
Solution 4 – 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.
Solution 5 – 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 previously installed version of Redistributables. After doing that, the issue was resolved completely.
Solution 6 – 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.
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.
Solution 7 – Perform in-place upgrade
If DLL files are missing from your PC, you might be able to fix the problem by performing an in-place upgrade. By doing so, you’ll reinstall Windows 10, but you will keep all your files and applications. This process is rather simple and you can do it by following these steps:
- Download Windows 10 ISO from Microsoft’s website. Be sure to download the latest version that matches your system architecture.
- Double click the ISO file to mount it. The new drive will now appear in This PC, open it and run setup.exe.
- Windows will now prepare the necessary files. You’ll be asked to download important updates before proceeding with the upgrade. Downloading updates isn’t mandatory, but it might make the upgrade process easier. Select the desired option and click Next.
- Windows will now download the necessary updates. This can take a while, so be patient.
- You should now see the Terms of Service screen. Click on Accept.
- Windows will now install the downloaded updates.
- Once you see Ready to install screen, click on Change what to keep.
- Select Keep personal files and apps and click on Next.
- Upgrade process will now start. This process can take a while, so don’t interrupt it.
Once your PC is upgraded, you’ll have a new installation of Windows 10, but all your files and applications will remain intact. If in-place upgrade can’t fix the problem, you might have to perform a Windows 10 reset. We already covered how to perform Windows 10 factory reset in one of our previous articles, so be sure to check it for detailed information.
