Versions:
msvcup is a lightweight, command-line installer utility developed by Jonathan Marler that downloads and configures the Microsoft Visual C++ (MSVC) compiler toolchain together with the Windows SDK without requiring the full Visual Studio IDE. Positioned in the compilers and SDK category, the program is offered in two numbered releases, the most recent being 2026_03_02. By treating the toolchain as a discrete, versioned asset instead of global system state, msvcup allows developers to embed a one-line call at the start of any build script and obtain a predictable, reproducible native compilation environment in milliseconds if the correct release is already cached. Each package is extracted to its own versioned directory, eliminating registry edits and side-by-side conflicts, while a generated lock file guarantees that every team member or continuous-integration worker compiles with identical headers, libraries and tools. Out-of-the-box support for x64, arm64 and x86 targets simplifies cross-compilation workflows, and the minimal download footprint fetches only the redistributable components actually needed to produce Windows binaries, saving bandwidth and disk space compared with the multi-gigabyte Visual Studio installer. The tool therefore suits open-source maintainers who want friction-free CI, corporate teams that must containerise legacy builds, and individual developers who prefer lightweight editors over heavy IDEs. msvcup is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
