  • The successor, released in 2021, is named Microsoft Visual C++ 2022 (part of Visual Studio 2022).

Below is a write-up covering the Visual C++ 2019 toolset and its transition into the 2021/2022 era.

How to Check if "Microsoft Visual C++ 2019 2021" is Installed

You have two easy methods to verify this specific component. The Evolution of Microsoft Visual C++: Understanding the

3.1 Key Features

  • C++17 conformance: ~95% complete (missing std::from_chars for floating-point, some parallel algorithms)
  • C++20 preview: Initial support for coroutines (co_await, co_yield, co_return), std::span
  • Build insights: New tool to analyze compilation time
  • AddressSanitizer (ASan) for Windows (experimental)

Error 1: "The application was unable to start correctly (0xc000007b)"

This usually happens when a 32-bit program tries to load a 64-bit DLL, or vice versa. It is often caused by a corrupted installation of Microsoft Visual C++ 2019 2021.

  • Fix: Uninstall ALL Visual C++ 2015-2022 runtimes (both x86 and x64) from your control panel, then restart and reinstall the latest "Visual C++ Redistributable" package from Microsoft's official website.

Microsoft Visual C++ 2019: The Bridge to Modern C++ Development

Microsoft Visual C++ 2019 (MSVC) represents a pivotal iteration of Microsoft’s compiler toolset. Shipped as part of Visual Studio 2019, it solidified Microsoft’s commitment to modern C++ standards, performance optimization, and cross-platform development. While the next major iteration, Visual Studio 2022, was released in late 2021, the 2019 toolset remains a critical standard for enterprise software and game development due to its stability and widespread deployment.

Microsoft Visual C++ (2019–2021): Ecosystem, Runtimes, and Development

The period between 2019 and 2021 was pivotal for Microsoft’s C++ ecosystem. While the core compiler toolset is technically known as MSVC (Microsoft Visual C++), users most often encounter it through two distinct avenues: the Visual Studio IDE (for developers) and the Visual C++ Redistributable (for end-users).

This write-up clarifies the state of Visual C++ during this era, covering the release of Visual Studio 2019, the evolution of the compiler standards, and the ongoing necessity of the Redistributable packages.

Method 2: Control Panel (Programs and Features)

  1. Open Control Panel > Programs > Programs and Features.
  2. Look for Microsoft Visual C++ 2019 Redistributable (x64) - 14.29.30133.
    • Build numbers starting with 14.28, 14.29, 14.30, 14.31, or 14.32 correspond to updates released in 2020 and 2021.
