What Causes Missing DLL File Errors?
Missing DLL errors usually occur due to:
- Accidental Deletion – The DLL file may have been removed during a software uninstall or system cleanup.
- Corrupt System Files – Windows system files can become corrupted due to crashes, malware, or hardware issues.
- Incomplete Software Installation – Some programs fail to install required DLL files properly.
- Windows Update Issues – Certain updates may remove or replace DLL files, causing compatibility problems.
- Malware Infections – Viruses and malware can delete or replace important DLL files.
- Hardware Failures – A failing hard drive or RAM issue can lead to missing or unreadable DLL files.
Step-by-Step Fixes
Method 1: Restart & Check Recycle Bin
Before making any major changes, restart your PC and check the Recycle Bin. If you accidentally deleted the DLL file, restore it.
Method 2: Use System File Checker (SFC)
SFC is a built-in Windows tool that scans and repairs corrupted system files.
- Open Command Prompt as an administrator.
- Type the following command and press Enter:
sfc /scannow - Wait for the process to complete, then restart your PC.
Method 3: Run DISM Command
If SFC fails to fix the issue, use the Deployment Image Servicing and Management (DISM) tool.
- Open Command Prompt as an administrator.
- Run the following command:
DISM /Online /Cleanup-Image /RestoreHealth - Restart your PC and check if the error is resolved.
Method 4: Reinstall the Affected Program
If the missing DLL error occurs when launching a specific application:
- Uninstall the program via Control Panel > Programs & Features.
- Download the latest version from the official website.
- Reinstall and check if the error persists.
Method 5: Download the Missing DLL File
If the missing DLL is application-specific, downloading it from a reputable source might help.
- Visit the official website of the software or Microsoft.
- Download and place the DLL file in the correct folder (usually
C:\Windows\System32). - Register the DLL file by running this command in the Command Prompt:
regsvr32 filename.dll
⚠ Warning: Avoid downloading DLL files from unknown third-party websites, as they may contain malware.
Method 6: Update Windows & Drivers
Outdated Windows or drivers can cause DLL issues.
- Open Settings > Windows Update and install available updates.
- Update drivers using Device Manager or manufacturer software.
- Restart your PC after updating to ensure the changes take effect.
Method 7: Perform a System Restore
If the error started recently, a system restore might help by rolling back changes.
- Type “Create a restore point” in the Windows search bar and open System Restore.
- Select Restore system files and settings.
- Choose a restore point before the error appears and follow the instructions.
Method 8: Reset or Reinstall Windows
If all else fails, resetting or reinstalling Windows can provide a fresh start.
- Open Settings > Update & Security > Recovery.
- Click Reset this PC and choose Keep my files or Remove everything.
- Follow the on-screen instructions to complete the process.
