The MSVCR71.dll is a dynamic link library file that is a part of the Microsoft Visual C++ runtime environment. This file is essential for running programs developed using Microsoft Visual C++ 2003. When this DLL file is missing from your Windows system, it can cause various issues and prevent certain applications from running properly. The error message MSVCR71.dll is missing usually appears when you try to launch a program that relies on this DLL file. The reasons for its absence can vary, but the most common causes are accidental deletion, improper software installation, or corruption of the file.
To resolve the issue, you can try the following solutions:
- Reinstall the application: If the error message appears for a specific program, try reinstalling it. Uninstall the program, download the latest version from the official website, and reinstall it. This process often replaces the missing DLL file.
- Update Microsoft Visual C++: Ensure that you have the latest version of Microsoft Visual C++ Redistributable Packages installed on your system. Visit the Microsoft website and download the appropriate version for your operating system. Install the package and restart your computer.
- Copy the DLL file from another source: Find a computer with the same operating system and copy the MSVCR71.dll file from its C:\Windows\System32 directory to the corresponding directory on your computer. Be cautious when obtaining DLL files from external sources, as they can be outdated or infected with malware. It is best to use a trusted source or extract the file from an original installation media.
- System File Checker: Windows has a built-in tool called System File Checker SFC that can scan for and restore missing or corrupted system files. Open the Command Prompt as an administrator and type sfc /scannow without quotes. This process may take some time, but it will attempt to repair any system files, including the msvcp140.dll missing.
- Windows Update: Ensure that your Windows operating system is up to date. Microsoft regularly releases updates that include bug fixes and security patches. Go to the Windows Update settings and check for any available updates. Install them and restart your computer if necessary.
