The libstdc++-6.dll not found error can occur when a program or application cannot locate the libstdc++-6.dll file in your system.

What is libstdc++-6.dll?

The libstdc++-6.dll file is a dynamic link library file created as part of the GNU Compiler Collection (GCC). This library provides the standard C++ functionality, including classes, functions, and templates, necessary for compiling and running C++ programs.

The libstdc++-6.dll missing error can happen due to several reasons:

  • Missing or deleted DLL file: The Libstdc++-6.dll file may be missing or accidentally deleted from its intended location.
  • Corrupted DLL file: The Libstdc++-6.dll file may become corrupted for various reasons, such as malware infection, hardware issues, or software conflicts.
  • Outdated software or incompatible version: If the software you are running requires a specific version of the Libstdc++-6.dll file and you have an outdated version or a conflicting version installed, it can result in the DLL not being found.
  • Software dependency issues: If a program or its dependencies are not correctly installed or configured, it can prevent other programs from finding the Libstdc++-6.dll file, as it is often a shared dependency.

How do I fix the libstdc++-6.dll not found error?

Before trying any advanced troubleshooting steps, follow these steps first:

  • Restore the DLL file from the Recycle Bin: If you accidentally deleted the DLL file, check your Recycle Bin. If you find it there, restore it to its original location.
  • Run a malware scan: Malware infections can corrupt the libstdc++-6.dll file. Running a thorough scan with reliable antivirus or anti-malware software can help detect and remove any malicious programs, potentially resolving the issue.
  • Reinstall the affected program: Most programs and games have necessary DLL files. If the libstdc++-6.dll file is missing or damaged, reinstalling the program that requires it may resolve the error.

1. Manually download the DLL file

  1. Go to official software websites or trusted DLL file repositories like the Dll file
  2. Download the DLL file that is compatible with your operating system version (32-bit or 64-bit).
