If that runtime is missing, your program is just shouting into the void. Do not download vcruntime140.dll from a "DLL download website." That is the digital equivalent of eating sushi off a gas station floor. Those files are often outdated, malicious, or simply wrong.

Let’s clear this up. You don’t need a single file. You need the . What is the "C++ Runtime," Anyway? Think of the C++ runtime as a shared library of instructions. When a developer writes a program in C++, they rely on standard building blocks (like code for math, strings, or file handling). Instead of packing those building blocks into every single program (which would waste space), the program says: "Call the runtime."

Now go back to launching your software. You’re welcome. Have a specific error code? Mention it in the comments below.

Your first instinct is to Google "C++ runtime download" —but you might end up confused by a dozen different versions (2005, 2008, 2010, 2015-2022) and a sea of shady "DLL download" sites.

If you’ve ever tried to launch a new video game, a proprietary corporate tool, or a cool open-source project from GitHub, you’ve likely been greeted by this frustrating popup: "The code execution cannot proceed because VCRUNTIME140.dll was not found." Or simply: "This program requires a C++ runtime."
