DLL file missing errors on Windows PCs can stop your important programs from running properly, causing frustration and delays. These errors happen due to reasons like corrupted system files, malware, bad software installations, or accidental deletions. In this blog, you will learn easy and effective ways to fix all missing DLL file errors on your Windows PC, including running system tools like SFC and DISM, reinstalling software, scanning for malware, and updating your Windows to keep everything running smoothly.
🔧 Step-by-Step Fixes for DLL File Missing Errors
1. Restart Your PC (Simple but sometimes effective)
Before diving into more technical solutions — always restart your computer once. Temporary glitches, incomplete update processes, or file locks can result in DLL errors that a simple reboot resolves.
2. Use System File Checker (SFC) to Repair Corrupted System DLLs
Windows comes with a built-in tool called System File Checker (SFC) that scans and restores corrupted or missing system files (including DLLs).
How to run:
- Press Win + X → choose Windows Terminal (Admin) or Command Prompt (Admin)
- Type:
sfc /scannowand press Enter - Wait until the scan completes (may take 10–30 minutes) — SFC will automatically replace missing/corrupted files when possible.
- After completion, restart your PC and check if the DLL error is resolved.
3. Use DISM to Repair Windows System Image
If SFC does not fix the issue (or reports problems it can’t repair), use the DISM tool to restore Windows image health. This helps when the core system components or DLL libraries are corrupted.
Steps:
- Open Command Prompt (Admin) or Windows Terminal (Admin)
- Run:
DISM /Online /Cleanup-Image /RestoreHealth - Wait for the process to finish.
- Then rerun
sfc /scannowafter DISM completes — sometimes both together solve DLL issues more reliably.
4. Reinstall the Affected Program (If Error Happens for a Specific App)
If the DLL error shows only when you open one particular application — reinstalling that software often fixes it. The installation package will restore all required DLLs that the program needs.
How to do:
- Go to Settings → Apps → Apps & features (or Control Panel → Programs)
- Uninstall the problematic app
- Reboot your PC
- Then download the latest version from the official site and install anew
This ensures a clean install with the correct DLL dependencies.
5. Install / Reinstall Microsoft Visual C++ Redistributables & Other Runtime Libraries
Many DLL errors (especially ones like MSVCP*.dll, VCRUNTIME*.dll, or other CRT / Runtime errors) are caused by missing or damaged Visual C++ redistributable packages.
What you should do:
- Visit the official Microsoft website
- Download and install the latest Visual C++ Redistributable packages — both x86 (32-bit) and x64 (64-bit) versions, even if your system is 64-bit.
- Restart your PC and try running the application again
Often, this restores missing DLLs that the application depends on.
6. Update Windows & Hardware Drivers
Outdated or incompatible system updates and drivers can cause DLL errors. Keeping Windows updated and drivers current helps restore essential system files and compatibility.
How to update:
- Go to Settings → Update & Security → Windows Update → click Check for updates and install all pending updates.
- Open Device Manager → check all hardware devices → optionally update device drivers if needed (especially graphics, audio, chipset drivers)
- Reboot after updates
7. Recover Deleted DLLs or Use Backup / System Restore
If the DLLs were accidentally deleted / removed — and you have a backup or previous restore point — you can recover them:
- Check Recycle Bin — restore if found (some DLL deletions are reversible).
- If you have a recent system backup or restore point — use System Restore to revert to a previous stable state before errors occurred.
Be cautious about manually downloading DLLs from random websites — these can be unsafe, incompatible, or harmful.
Conclusion
DLL missing errors are common on Windows, but in most cases they’re not permanent — Windows includes powerful built-in tools (SFC, DISM), and reinstalling software or installing necessary runtime libraries often fixes the problem. By following the steps above carefully, you can restore missing DLL files and get your programs working again — without relying on shady third-party DLL download sites.
