Missing DLL Errors
“DLL not found” usually means a missing dependency or corrupted system file. Follow these steps to restore required components.
Install Runtimes
- Install/repair Microsoft Visual C++ Redistributables (x86/x64).
- Install/repair .NET Desktop Runtime matching the app’s requirement.
- Update DirectX Runtime if the error is graphics-related (d3dx*.dll).
Warning: Avoid downloading individual DLLs from third-party sites — use official installers only.
Repair System Files
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
Tip: Reboot after SFC/DISM and retest the application.
App-Specific Fixes
- Reinstall the affected app (its installer often deploys the needed DLLs).
- Check Event Viewer for the exact DLL name and version.
- If portable apps fail, install the full version.
