C++ program not running on windows systems without VS installed “VCRUNTIME140.dll was not found”

问题

When I compile a simple program:

#include <iostream>

using namespace std;
void main() {
    cout << "Hello world!";
}

And tun the compiled .exe on another system without visual studio installed I receive the following error:

The Code execution cannot proceed because VCRUNTIME140.dll was not found. Reinstalling the program may fix the problem.

When I compile with cl.exe I receive no errors, does anyone know a workaround to this without installing VCRUNTIME140.dll on the systems. (I've tested on multiple windows systems including a windows virtual machine)

回答1:

Get the "Visual Studio 20xx VC++ Redistributable package" for your version of Visual Studio. Then run on the target machine to install.

Bottom of this page: https://visualstudio.microsoft.com/downloads/

Or bottom of this page for older versions of Visual Studio: https://visualstudio.microsoft.com/vs/older-downloads/

I've encountered this problem before and there's a simple solution to it,

The missing .dll are a issue of static linking not missing packages (in most cases), becuase visual studio 2019 comes pre-installed with what you need.

To fix: go to your project properties (in project tab) Select C/C++ Change the value of runtime library to "Multi-threaded debug (/MTd)"

This will cause the compiler to embed the runtime into the app. The executable will be significantly bigger, but it will run without any need of runtime dlls.
