Visual Studio Runtime [verified] -

# GitHub Actions example - name: Install VC++ Redist run: | curl -L -o vc_redist.exe https://aka.ms/vs/17/release/vc_redist.x64.exe .\vc_redist.exe /install /quiet /norestart Or use the pre-installed Visual Studio image that already has runtimes. The Visual Studio Runtime isn’t magic or mysterious. It’s just a system DLL that Microsoft expects you to redistribute.

If you’ve ever double-clicked a freshly built .exe only to be greeted by “The code execution cannot proceed because VCRUNTIME140.dll was not found” — you’ve met the Visual Studio Runtime. visual studio runtime

It’s frustrating. But once you understand what this runtime actually is , that error becomes easy to prevent and fix. In simple terms: when you write C++ code (or use libraries written in C++), your program relies on standard functions like printf , malloc , or memcpy . The Visual C++ Runtime is the DLL that provides those functions at runtime. # GitHub Actions example - name: Install VC++

dumpbin /dependents MyApp.exe Look for VCRUNTIME140.dll . That tells you your app requires the VS 2015+ runtime. | Symptom | Likely Cause | Fix | |--------|--------------|-----| | Error on customer’s PC, works on yours | Missing redist | Install VC++ redist on target PC | | Error after Windows update | Runtime got uninstalled by cleanup | Reinstall redist | | Error with Python/node native module | Module built with newer VS | Install matching VS Build Tools | | Portable app won’t run on fresh Windows | No runtime installed | Use static linking or app-local DLLs | One Weird Trick for CI/CD If you’re building on a fresh build agent (GitHub Actions, Azure DevOps, Jenkins), don’t assume the runtime is present . Always install the redistributable as part of your build setup: If you’ve ever double-clicked a freshly built

C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Redist\MSVC\v143\ This works well for portable apps. Use Dependency Walker or the built-in dumpbin tool:

Instead of embedding (statically linking) that code into every single .exe (which wastes disk space and memory), Windows loads a shared DLL: VCRUNTIME140.dll .

End users don’t have Visual Studio. So you have to ship the runtime. 1. Ship the Redistributable (Most Common) Microsoft provides official redistributable packages. Bundle them with your installer.
