The “Entry Point Not Found” error is a common issue in Windows that occurs when a program or system file fails to locate a necessary function within a dynamic link library (DLL). This error can prevent software from running properly, leading to frustration for users. If you’re facing this issue, don’t worry! In this guide, we’ll explore the causes of this error and the most effective methods to fix it.
What Causes the “Entry Point Not Found” Error?
This error can be caused by several factors, including:
- Corrupt or missing DLL files: If a required DLL file is missing or damaged, the program won’t be able to execute the necessary functions.
- Incorrect DLL version: Some programs require specific DLL versions, and an outdated or incompatible version may trigger this error.
- Incomplete installation: If a software installation wasn’t completed properly, essential files might be missing.
- Malware infection: Certain types of malware can corrupt or replace critical DLL files, leading to this error.
- Conflicting software updates: Windows updates or software patches can sometimes introduce compatibility issues.
Now that we understand the causes, let’s move on to the solutions.
How to Fix the “Entry Point Not Found” Error
1. Restart Your Computer
Before diving into complex solutions, try restarting your system. Sometimes, a simple reboot can resolve temporary glitches and DLL errors.
2. Reinstall the Problematic Application
If you encounter this error while launching a specific program, try reinstalling it:
- Press Windows + R, type appwiz.cpl, and press Enter.
- Find the affected program, right-click on it, and select Uninstall.
- Once removed, download the latest version from the official website and reinstall it.
3. Replace the Corrupt or Missing DLL File
Sometimes, replacing the affected DLL file can resolve the issue:
- Identify the missing DLL from the error message (e.g., MSVCR100.dll).
- Download a genuine version of the DLL from the official Microsoft website.
- Copy the file to C:\Windows\System32 (for 32-bit systems) or C:\Windows\SysWOW64 (for 64-bit systems).
- Restart your computer and check if the error persists.
Note: Avoid downloading DLL files from third-party websites, as they may contain malware.

4. Run System File Checker (SFC) Scan
Windows includes a built-in tool to scan and repair corrupt system files. Here’s how to use it:
- Press Windows + S, type cmd, and select Run as administrator.
- In the Command Prompt, type the following and press Enter:
sfc /scannow
- Wait for the process to complete and restart your computer.
This will automatically detect and repair corrupt files, potentially resolving the error.
5. Perform a Windows Update
Outdated system files can sometimes cause entry point errors. Updating your Windows version can help:
- Press Windows + I to open Settings.
- Go to Update & Security and click Check for updates.
- Install any available updates and restart your computer.
6. Scan for Malware
Malware infections can corrupt DLL files, leading to errors. Running a virus scan can help:
- Open Windows Security by searching for it in the Start menu.
- Go to Virus & threat protection and click Quick scan.
- If threats are found, remove them and restart your system.

7. Use the Dependency Walker Tool
If you’re unsure which DLL is causing the error, the Dependency Walker tool can help:
- Download Dependency Walker from a trusted source.
- Run the program and open the affected application’s executable file.
- The tool will list missing or corrupted DLL files, allowing you to replace them accordingly.
