However, many tools and documentation still refer to the original 14.0 version because it was the baseline for this compatibility guarantee. When a developer writes a C++ application using Visual Studio, they often link to runtime libraries (e.g., vcruntime140.dll , msvcp140.dll ). These DLLs contain standard C and C++ functions like malloc , printf , std::vector , etc.
Introduction If you have ever installed a modern application on Windows—especially software related to data science, game modding, or Python packages—you may have encountered an error message mentioning “Microsoft Visual C++ 14.0 is required.” Despite its specific version number, Visual C++ 14.0 is not an obscure, legacy tool. In fact, it is a core component of Microsoft’s C++ compiler and runtime library ecosystem, still widely used today. microsoft visual c 14.0
pip install --global-option=build_ext --global-option="-IC:\Program Files (x86)\Microsoft Visual Studio\..." package_name But modern pip and setuptools usually detect Visual Studio automatically. For Python users, the easiest fix is to avoid building from source altogether. Install a precompiled wheel: However, many tools and documentation still refer to
pip install --only-binary :all: package_name Or upgrade pip and setuptools : Introduction If you have ever installed a modern
Instead of bundling these DLLs with every app (which would waste disk space and cause version conflicts), Microsoft distributes them via the . The user must install the appropriate redistributable before running the application.
| Visual Studio Version | Internal Toolset Version | Microsoft Visual C++ Redistributable | |----------------------|--------------------------|----------------------------------------| | Visual Studio 2015 | 14.0 | VC++ 2015 Redistributable | | Visual Studio 2017 | 14.1 | VC++ 2017 Redistributable (binary-compatible with 14.0) | | Visual Studio 2019 | 14.2 | VC++ 2019 Redistributable | | Visual Studio 2022 | 14.3 | VC++ 2022 Redistributable |
Starting with Visual Studio 2015 (14.0), Microsoft made the runtime libraries binary compatible across versions 2015, 2017, 2019, and 2022. This means an application compiled with Visual C++ 14.0 can run on a system that has the 2015, 2017, 2019, or 2022 redistributable installed.
