How to Fix DLL Errors on Windows

DLL errors usually mean a program can’t find, load, or use a required .dll file. This can happen after a bad app uninstall, a failed update, malware damage, corrupted system files, or when software leaves behind broken registry entries and file paths. In many cases, the DLL itself is not the real problem—the issue is an incomplete install or leftover software traces pointing to files that no longer exist.

Common Symptoms

• A pop-up says a specific DLL file is missing, not found, or failed to load
• A program crashes at launch or won’t open at all
• Windows shows errors after startup, login, or shutdown
• Games or apps stop working after an update or uninstall
• You see messages like “The code execution cannot proceed” or “Entry point not found”

How to Fix It Manually

1. Restart your PC

   • A temporary file lock or failed startup process can trigger DLL errors.
   • Click Start > Power > Restart and try opening the app again.

2. Reinstall the program showing the DLL error

   • Press Windows + I to open Settings.
   • Go to Apps > Installed apps.
   • Find the affected app, click the three dots, then choose Uninstall.
   • Restart your PC, then download and install the latest version from the software maker’s official site.
   • If the error started after uninstalling another program, reinstalling the affected app may restore missing shared files.

3. Repair Windows system files

   • Click Start, type cmd.
   • Right-click Command Prompt and choose Run as administrator.
   • Run this command:

     sfc /scannow

   • Wait for the scan to finish. If it finds and repairs files, restart your PC.
   • Then run:

     DISM /Online /Cleanup-Image /RestoreHealth

   • Restart again after DISM completes.

4. Install Windows updates

   • Press Windows + I and go to Windows Update.
   • Click Check for updates.
   • Install all available updates, including optional driver or runtime updates if relevant.
   • Restart your PC after updates finish.

5. Check for malware

   • Open Windows Security from the Start menu.
   • Go to Virus & threat protection.
   • Click Scan options and run a Full scan.
   • Malware can delete, replace, or block DLL files, so this step matters if the error appeared suddenly.

6. Reinstall Microsoft Visual C++ Redistributables if the error affects apps or games

   • Many programs depend on these runtime DLLs.
   • Open Settings > Apps > Installed apps and look for Microsoft Visual C++ Redistributable entries.
   • You can try Modify > Repair if available.
   • If that doesn’t help, download the latest supported Visual C++ Redistributables from Microsoft and install both x64 and x86 versions if your software needs them.

7. Remove leftover startup entries or broken software traces

   • Open Task Manager with Ctrl + Shift + Esc.
   • Go to the Startup apps tab and disable entries tied to software you already removed.
   • Then press Windows + R, type appwiz.cpl, and check whether the problem app or related tool is still partially installed.
   • Leftover entries can keep calling DLL files that were deleted during an incomplete uninstall.
