Microsoft Visual C++ Redistributable packages. These are required to run applications built with Visual C++ that are not already present on your system. Latest Official Downloads (Microsoft) The most current versions are bundled into a single installer for versions 2015 through 2022. You should choose the download based on your system's architecture: Visual Studio 2015, 2017, 2019, and 2022 (x64) : For 64-bit Windows systems. Visual Studio 2015, 2017, 2019, and 2022 (x86) : For 32-bit Windows systems. Visual Studio 2015, 2017, 2019, and 2022 (ARM64) : For Windows on ARM devices. Microsoft Learn +2 Legacy Versions Some older software may require specific legacy runtimes: Visual C++ 2013 : Used for older apps from the early 2010s. Visual C++ 2012 : Update 4 is the latest supported for this version. Visual C++ 2010 SP1 : Often required by Windows XP/Vista era software.

Prior to Visual Studio 2015, the runtime was largely monolithic. If a developer built an application with Visual Studio 2012, the user required the specific 2012 runtime. This led to the proliferation of multiple "Microsoft Visual C++ Redistributable" entries in a user's "Add/Remove Programs" list, often resulting in systems having five to ten different runtime versions installed simultaneously.

The only official source is .

With the release of Visual Studio 2015, Microsoft introduced the Universal C Runtime. This separated the standard C library ( ucrtbase.dll ) from the compiler-specific code ( vcruntime and msvcp ). The UCRT is now a Windows component, often delivered via Windows Update. This architectural shift reduced the frequency of specific downloads but complicated the diagnosis when an older OS version lacks the specific Windows Update required.

Think of the C++ runtime as a shared library of instructions. When a developer writes a program in C++, they rely on standard building blocks (like code for math, strings, or file handling). Instead of packing those building blocks into every single program (which would waste space), the program says: "Call the runtime."
