While binary compatibility holds for most functions, a program compiled with VS 2022's latest C++17/20 features might call a newer exported function not present in the 2015 redist. That's why the installer merges upward – the latest version contains all older exports. microsoft visual c 2015-2022

They introduced a binary-compatible runtime across all future versions (2015, 2017, 2019, 2022). The internal versioning scheme (v14.0 → v14.1 → v14.2 → v14.3) all share the same core DLL names, file structures, and ABIs (Application Binary Interfaces). | Visual Studio | Runtime Version | vcruntime140

Microsoft has not fully consolidated the installer metadata, leading to this cosmetic clutter. You can safely uninstall older named versions if the latest is present – but Windows will complain if an app's installer explicitly checks for a specific ProductCode. A common developer mistake: compiling with /MDd (debug runtime) and expecting the redistributable to provide the necessary DLLs. It won't. Debug builds require msvcp140d.dll , vcruntime140d.dll – these are not shipped in the redist and are only available with Visual Studio installation. The internal versioning scheme (v14

But next time you see that installer pop up, know that you're looking at one of the most successful long-term backward compatibility efforts in computing history.

Each had its own file paths, DLLs, and quirks. This led to "DLL hell" on Windows: applications would install their required version, sometimes overwriting others, causing mysterious crashes.
