The `msvcr120d.dll` is a Dynamic Link Library (DLL) file associated with the Microsoft Visual C++ Redistributable for Visual Studio 2013. The "msvcr" prefix stands for Microsoft Visual C Runtime, and the "120" indicates its association with Visual Studio 2013. The "d" at the end of the filename signifies that this is a debug version of the library, which contains additional debugging information useful for developers during the development and testing phases of an application.
Debug versions of runtime libraries like `msvcr120d.dll` are used to facilitate the debugging process, providing detailed error messages, supporting the inspection of variables and memory states, and allowing the use of breakpoints in the code. These features help developers identify and fix bugs in their applications more efficiently. However, debug versions are not intended for use in production environments due to their larger size and reduced performance, as they are optimized for debugging rather than speed or efficiency.
This DLL is essential for applications developed with Visual Studio 2013 that depend on this specific version of the C++ runtime during their development and debugging processes. It provides the runtime components necessary to execute C++ applications that utilize advanced features or updates introduced in Visual Studio 2013.
If developers encounter issues with `msvcr120d.dll`, such as error messages indicating the DLL is missing or has encountered an error, it could disrupt the development or debugging of C++ applications. Resolving such issues typically involves ensuring that the correct version of the Microsoft Visual C++ Redistributable for Visual Studio 2013 is installed and properly configured in the development environment. However, it's important to switch to the release version of these libraries when creating the release build of an application to ensure optimal performance and compatibility.
