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.


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 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 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.


What can I do if a DLL file is missing from my Windows 10?

  1. Run a third-party DLL fixer
  2. Run SFC Scanner
  3. Run DISM
  4. Download a DLL File Manually
  5. Install DirectX
  6. Reinstall Visual C++ Redistributables
  7. Disable or remove your antivirus
  8. Perform in-place upgrade

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.

However, if you are to choose just one, then there’s no way you can go wrong with Restoro.

Among plenty of other great features that help with PC optimizations, Restoro will replace your missing or damaged DLL files with fresh, clean, and up-to-date ones.

It does this by comparing your DLL database with one of its own, and that is also where it gets the missing DLLs from too.

DLLs and registries are valuable data libraries that Windows uses in order to run properly. Because of that, damaged or missing dlls or registry keys can be a leading cause for crashes, freezes, error messages, and they can even prevent you from launching software and Windows features altogether. Unfortunately, registries and DLLs are clusters of data that even advanced users have a hard time tweaking properly without guidance, and even Microsoft advices against it. More so, resetting your Windows OS is among the only truly effective solutions to fix these errors, but this solution has far too many drawbacks.

In order to avoid all that, one can always rely on automated third-party solutions, and few are as good as Restoro. It automates pretty much every aspect of your PC repair process, from the scans to the actual fixing. Follow this small guide to learn to you can restore your PC to peak performance using Restoro:
  1. Download and install Restoro.
  2. Launch Restoro.
    • Restoro will now compile data about your PC.

  5. Restart your PC for all the changes to take effect.
Your PC should now work perfectly fine, and you will no longer have to worry about slow response times, BSoD errors, or anything of the sort. Disclaimer: This program needs to be upgraded from the free version in order to perform some specific actions.

2. Run SFC Scanner

  1. Right-click on the Start Menu button, and choose Command Prompt (Admin).
    Sysmenu dll file missing cmd admin
  2. Enter the following command and press Enter:
  • sfc/scannow
    Msvcr100.dll file missing error sfc/scannow cmd
  1. Wait for the process to finish (it may take a while because it will scan your whole system for errors).
  2. Restart your computer.
  3. 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

  1. Run Administrative Command Prompt (as shown above).
  2. Enter the following command into the Command Prompt, and press Enter: DISM /Online /Cleanup-Image /RestoreHealth
    T8extpex.dll file is missing DISM cmd
  1. Wait for the process to finish.
  2. 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.
