DLL files are crucial for various apps and services in Windows. With that in mind, stumbling upon DLL errors may be disturbing, but fear not, as we’re here to help you deal with them.

We’ll explore how to fix DLL errors in Windows 10 and 11, restore missing DLL files, and tackle other common DLL-related issues. From simple solutions to advanced measures, by the end of this article, we’ll equip you with necessary tools to resolve your DLL errors once and for all.

Note: DLL stands for Dynamic Link Library, and you can compare a .dll file to a real-life library book, which any reader can get certain knowledge from. Each .dll file contains code and data crucial for operation of various apps and services.

Before Anything Else…

Before you proceed to the troubleshooting methods, we recommend trying a few simple fixes outlined below.

Restart your PC

In some cases, a simple reboot may fix .dll errors on your PC. However, it may only work if you can launch Windows.

Restore the missing .dll files from the Recycle Bin

One of the possible causes of “.dll was not found” and “.dll is missing” errors is that you accidentally deleted them. In this case simply go to your Recycle Bin, search for and restore missing dynamic link library files. If your OS can’t launch normally, enter Safe Mode to perform this step.

Now, if after trying these simple solutions the DLL error still persists, move on to the methods below.

Method 1: Scan for malware

One of the possible reasons for a “.dll not found” error is that your system was compromised by malware. Consider using reliable antivirus software, such as Auslogics Anti-Malware, to fix DLL errors and keep your system secure. This tool can work alongside your primary antivirus, strengthening your protection against cyberthreats.

Method 2: Use System Restore

It is possible that a recent update or change in your system configuration or registry caused the DLL error. If this is the case, it’s advisable to roll back your system to a restore point where everything was working fine. However, you need to have a previously created restore point to roll back to. Here’s a brief instruction on how to fix DLL errors by restoring your system:

  • Enter “Control Panel” in the search bar and click on the top result.
  • In the upper right corner, find the “View by” section and choose “Large icons.”
  • Click on “Recovery,” then click on “Open System Restore,” and follow the prompts in the new window.
  • Finally, click on “Finish” to run System Restore.

Method 3: Run an SFC scan

Windows 10 and 11 come with the built-in System File Checker (SFC) tool that you can use to troubleshoot common problems, including “corrupt DLL” or “missing DLL” errors. Try performing an SFC scan to make sure that all damaged or affected Microsoft-supplied DLL files are replaced properly.

Here’s how to fix missing DLL files by running the System File Checker:

  • On your keyboard, press “Windows key + S.”
  • Type “cmd” (no quotes).
  • From the results, you will see “Command Prompt.” Right-click it, then select “Run as administrator.”
  • Once the Command Prompt is open, type “sfc /scannow” (no quotes), and press Enter.
Run command prompt as admin

The process will take several minutes to complete. Stay patient and avoid interrupting it. Once it is done, check if DLL errors are gone.

Method 4: Apply Windows updates

Windows updates and service packs generally come with hundreds of Microsoft DLL files that will replace or update your missing DLL files.

Here’s how to fix DLL errors in Windows 10 by applying Windows updates:

Method 5: Reinstall the program that uses the DLL file

If you face a “.dll not found” error when trying to run a certain program, consider reinstalling it. This should properly install and register the problematic file, ultimately fixing .dll errors. Here’s how to do it:

  • Enter “Control Panel” in the search bar and click on the top result.
  • Click on “Uninstall a program” under “Programs.”
  • Right-click the problematic program and select “Uninstall.”
  • Follow the instructions to delete the program.

Finally, visit the official website or a trusted source, download, and install the program from scratch.

Method 6: Update drivers

Faulty or outdated drivers sometimes may cause “.dll was not found” and other DLL-related errors. To rule out this possibility, you need to update your drivers.

Since you don’t know which driver is to blame, you’ll need to check and update all your devices’ drivers. Doing this manually will be excessively time-consuming, while not guaranteeing the positive outcome. Thankfully, there is a way to update your drivers automatically with their latest official versions.

Auslogics Driver Updater is a reputable tool that will scan your system, locate outdated or problematic drivers, and install the most current version for each with a click of a button. The program backs up your drivers before installing new ones, ensuring your system security. All in all, Auslogics Driver Updater is a reliable solution to help keep your PC performing at its best.
