2. Step-by-Step Instructions to Fix msvcp120.dll Errors

If you are encountering msvcp120.dll errors, here is a practical and safe troubleshooting guide:

1. Check Your Recycle Bin

   Start by opening the Recycle Bin and searching for msvcp120.dll. It’s possible you may have accidentally deleted the file, and restoring it can solve the issue quickly.

2. Restart Your Computer

   Before proceeding with complex fixes, restart your PC. Sometimes, the error is temporary and related to a system or program glitch.

3. Reinstall the Microsoft Visual C++ Redistributable

   Since msvcp120.dll is part of the Visual C++ 2013 Redist, the proper and recommended method for restoring the file is to reinstall the package:

   • Visit the official Microsoft download page for the Visual C++ Redistributable Packages for Visual Studio 2013.
   • Download both the x86 (vc_redist.x86.exe) and x64 (vc_redist.x64.exe) installers, regardless of your system architecture, since different programs may require different versions.
   • Close all open applications and run both installers, following the on-screen instructions.
   • Reboot your computer after installation.

   Avoid downloading msvcp120.dll individually from unverified third-party sites; these sources may provide outdated, incompatible, or malicious files.

4. Update Your Software and Windows

   Some applications or games that depend on msvcp120.dll may require specific updates. Ensure all relevant software and your Windows operating system are fully updated. Run Windows Update and check for application-specific updates or patches.

5. Run a System File Checker (SFC) Scan

   Corruption in system files can trigger DLL errors. Use the built-in SFC utility to scan and automatically repair system files:

   • Open Command Prompt as an administrator (search “cmd”, right-click, select “Run as administrator”).
   • Type sfc /scannow and press Enter.
   • Wait for the scan to complete and follow any prompts to repair files.
   • Reboot your PC once done.
6. Check for Malware

   Run a comprehensive scan using Windows Defender or your preferred antivirus to rule out infections causing the error. Many types of malware target DLL files to disrupt key operations or disable security programs.

7. Reinstall the Affected Program

   Sometimes, the problem can be app-specific. Uninstall the application that is triggering the msvcp120.dll error, restart your computer, and then reinstall the program. This step can resolve any localized file corruption or compatibility issues.

8. Restore Your System

   If the error appeared after a recent update, driver installation, or software change, you can attempt a System Restore to revert your PC to a prior state:

   • Type “System Restore” in Windows search and select “Create a restore point.”
   • Click “System Restore” and follow the prompts to select a restore point dated before the appearance of the msvcp120.dll error.
   • Confirm the restore and allow Windows to restart.
9. Seek Office or Developer Support

   If these steps do not resolve the issue, consult the support forums or help center for the software in question. Developers may provide patched installers or specific troubleshooting instructions for msvcp120.dll problems.

3. Conclusion

Encountering an msvcp120.dll error can be frustrating, particularly when it halts the launch of critical programs or games. Fortunately, most instances originate from missing or damaged Visual C++ libraries, and the solution is straightforward: reinstall the proper Microsoft Visual C++ 2013 Redistributable package. Complementary steps such as performing virus scans, updating Windows, running the System File Checker, and reinstalling the afflicted application will address a wide range of scenarios contributing to this error.

It’s important to avoid the shortcut of downloading DLL files from unofficial sources, as this introduces significant risks and rarely addresses the underlying issue. Instead, relying on official Microsoft resources and following best practices ensures the long-term integrity and stability of your Windows system. If persistent problems arise, engaging with application developer support may provide the final resolution. By following these structured steps, you can restore normal operations and prevent future msvcp120.dll errors.
