Microsoft does not practice "backward compatibility" for C++ runtimes the way it does for standard Windows APIs.
Microsoft Visual C++ is a proprietary compiler for C++, C, and assembly, part of the Visual Studio IDE. Version 16.0 (2019) was released on April 2, 2019. Subsequent updates (16.8 through 16.11, released across 2020–2021) delivered critical changes often collectively referred to as “MSVC 2021” in developer communities. This paper analyzes:

Microsoft changed how it distributes runtime files starting with Visual Studio 2015. Instead of creating separate, isolated packages for every annual release, they built a unified architecture.
Each version (e.g., 2008, 2010, 2015-2022) is required by specific, older, or younger applications. Removing them can break installed software. Common Issues:
Choose the version that matches your system architecture: x64: For 64-bit Windows (most common). x86: For 32-bit Windows. ARM64: For ARM-based devices. Download & Install: Download the .exe file and run it.
Right-click the (do this for both x86 and x64 if present). Click Change , then click Repair . Restart your computer once the process finishes. Method 2: Clean Reinstallation
