- Question from Kumar

The "Entry Point Not Found" error is a common Dynamic Link Library (DLL) error in Windows 11 that usually appears when you try to launch an application, game, or system utility. The error message typically states that "a specific procedure entry point could not be located in a DLL file, preventing the program from starting correctly". It often occurs after a Windows update, software installation, application upgrade, or changes to system files.

Entry Point not Found

Fortunately, this error is usually caused by software or system file issues rather than hardware failure. In this guide, you'll learn the most common reasons behind the and follow step-by-step solutions to repair corrupted DLL files, restore missing system components, and get your applications running normally again.

Why Does "Entry Point Not Found" Appear in Windows 11?

An "Entry Point Not Found" error occurs when a program cannot locate the specific function (entry point) it expects within a Dynamic Link Library (DLL) file. This usually means the application and the DLL version are incompatible, or the required system files have been modified, corrupted, or replaced. The most common causes include:

Corrupted or missing DLL files: Essential DLL files may become damaged due to disk errors, malware, or unexpected system shutdowns.

Software version mismatch: A program may be trying to load an older or newer DLL that doesn't contain the required entry point.

Incomplete software installation or update: If an application is not installed or updated properly, some DLL files may be missing or incorrectly registered.

Corrupted Windows system files: Damaged system components can prevent applications from accessing the required DLL functions.

Faulty Windows updates: In some cases, a Windows update may replace or modify system libraries, causing compatibility issues with existing software.

Outdated Visual C++ Redistributables: Many applications rely on Microsoft Visual C++ runtime libraries. If they are missing or outdated, DLL-related errors may occur.

Third-party software conflicts: Registry cleaners, DLL replacement tools, or unofficial software modifications can overwrite system DLLs and trigger entry point errors.

How to Fix Entry Point Not Found in Windows 11/10/7/8

Since the "Entry Point Not Found" error can result from application conflicts, missing DLL files, corrupted system components, or incompatible updates, it is best to troubleshoot from the simplest solutions before moving to advanced system repairs. Follow the methods below in order until the error is resolved.

Method 1. Reinstall the Affected Program

In many cases, the error is caused by an incomplete installation or a version mismatch between the application and its required DLL files. Reinstalling the program replaces missing or damaged files with fresh copies and ensures the application is correctly registered with Windows. This is the quickest solution if the error only affects one specific program.

Step 1. Press "Win" + "R" and type "appwiz.cpl" in the Run dialog, then hit the "Enter" key to open Programs and Features.

Step 2. Find the affected application from the list and right click on it, then choose "Uninstall".

Step 3. Restart your computer after the uninstallation is complete.

Step 4. Download the latest version of the application from its official website and install it.

Step 5. Launch the program to verify whether the error has disappeared.

Method 2. Disable Windows Defender Temporarily

Sometimes Windows Defender or another antivirus program may mistakenly quarantine a required DLL file, preventing an application from loading correctly. Temporarily disabling real-time protection helps determine whether security software is causing the issue. If the application works afterward, you can restore the quarantined file and add it to the exclusion list instead of leaving protection disabled.

Step 1. Open "Windows Security" from the "Start" menu.

Step 2. Select "Virus & threat protection".

Step 3. Click "Manage settings" under "Virus & threat protection" settings.

Step 4. Turn "Real-time protection" off temporarily.

Step 5. Run the affected application again to see whether the "Entry point not found" error is resolved.

★Tips:
Re-enable Windows Defender immediately after testing to keep your computer protected.

Method 3. Restore the Quarantined DLL File

If Windows Defender has quarantined a DLL that your application depends on, restoring it may immediately resolve the Entry Point Not Found error. After restoring the file, you should add it to the exclusion list if you trust the application. Only restore DLL files that belong to legitimate software from reliable sources.

Step 2. Navigate to "Windows Security" > "Virus & threat protection" > "Protection history".

Step 3. Look for recently quarantined DLL files related to the affected application.

Step 4. Select the DLL file and click "Quarantined Items" by "Filters".

Step 5. Go to "Virus & threat protection" settings > "Add or remove exclusions" and add the application's installation folder or DLL file.

Add or Remove Exclusions

Step 6. Restart the application and verify that the error no longer appears.

Method 4. Recover Missing DLL Files with MyRecover

If the "Entry Point Not Found" error is caused by a missing DLL file that was accidentally deleted, removed during disk cleanup, lost after formatting, or disappeared because of file system corruption, recovering the original DLL file may resolve the issue. Before making further system changes, it's worth checking whether the missing DLL can be restored. MyRecover is a professional Windows data recovery tool that can recover deleted DLL files as well as other lost documents, photos, videos, and application files from HDDs, SSDs, USB drives, and other storage devices.

Method 5. Run DISM and SFC Commands

If Windows system files have become corrupted, repairing them can resolve many DLL-related errors. DISM repairs the Windows component store, while SFC scans and replaces damaged system files using healthy copies. Running both tools together is one of the most effective ways to fix system-level "Entry Point Not Found" errors.

Step 1. Type "Command Prompt" in the Start menu, right-click on it, and choose "Run as administrator".

run cmd as administrator

Step 2. Run the following command one by one. Proceed to the next command only after the former one hits 100% completion:

  • DISM /Online /Cleanup-Image /RestoreHealth
  • sfc /scannow

sfc scannow

Step 3. Restart your computer after both scans finish.

Step 4. Launch the affected application to check whether the error is fixed.

Method 6. Update Visual C++ Redistributable Packages

Many Windows applications rely on Microsoft Visual C++ Redistributable packages to access shared runtime libraries. If these components are outdated, corrupted, or missing, the application may fail to locate the required DLL entry point. Installing the latest supported packages often resolves compatibility problems without reinstalling Windows.

Step 1. Open "Settings" > "Apps" and review the installed Microsoft Visual C++ Redistributable versions.

Step 2. Download the latest supported Visual C++ Redistributables from Microsoft's official website.

download mv c++ 2010 redistributable

Step 3. Install both the x64 and x86 versions if your system requires them.

Step 4. Restart your computer after installation.

Step 5. Open the affected application and check whether the DLL error has been resolved.

Method 7. Check for Recent Windows Updates

If the error started after a Windows update, the update may have introduced compatibility issues with older software. Conversely, if your system has not been updated for a long time, installing the latest updates may provide bug fixes that resolve DLL-related problems. Reviewing recent updates helps determine which situation applies.

Step 1. Open "Settings" > "Update & Security" > "Windows Update".

Step 2. Click "Check for updates" and install any available updates.
