Vcruntime140_1.dll Missing or Not Found: How to Fix It

vcruntime140_1.dll missing or not found almost always means the Microsoft Visual C++ Redistributable is absent or damaged. 


The fix is to reinstall that redistributable, not hunt down the single file. Here is what the file does and how to get it working again.


What Is vcruntime140_1.dll?


vcruntime140_1.dll is a Microsoft C Runtime Library file, published by Microsoft as part of the Visual C++ 2015 to 2019 runtime family.


It provides code that other Windows programs rely on so they don't have to package it themselves. 


Many applications require these redistributable runtime packages to function correctly, according to Wikipedia, since installing them separately lets multiple programs share the same code instead of each bundling its own copy. 


In practice, most people never notice this file until a program that depends on it can't find it.


Common vcruntime140_1.dll Error Messages

  • The program can't start because vcruntime140_1.dll is missing from your computer.

  • The code execution cannot proceed because vcruntime140_1.dll was not found.

  • There was a problem starting vcruntime140_1.dll. The specified module could not be found.


The wording changes by program, but the cause is usually the same.



Why the vcruntime140_1.dll Error Happens

  • The Visual C++ Redistributable that includes this file was never installed, or was removed.

  • An application installed incompletely, so its runtime files never landed on the system.

  • The wrong architecture is installed. This file needs the 64-bit (x64) redistributable. The 32-bit (x86) package doesn't contain it.


Support teams commonly report that architecture mismatch is the quiet cause behind a lot of these tickets.


How to Fix vcruntime140_1.dll Is Missing


Step 1: Reinstall the Microsoft Visual C++ Redistributable


Run the official redistributable installer, named vc_redist.x64.exe, rather than sourcing the DLL on its own.


Package

Contains vcruntime140_1.dll?

When to use it

x64 (64-bit)

Yes

Nearly all modern Windows PCs

x86 (32-bit)

No

Legacy 32-bit software only


If a version is already installed, uninstall it first, then run the installer again. A repair install sometimes isn't enough.


Step 2: Reinstall or Repair the Affected Program


If the redistributable is already current, the program itself may have installed incompletely. Reinstalling it, or using a built-in repair option, often restores the missing files. 


This is common with interrupted Office installs.



Step 3: Restart Your Computer


A restart after installing runtime files matters more than people expect. Some processes hold onto the old, broken state until the system reloads.


Should You Download vcruntime140_1.dll Directly?


It's tempting, but in practice this usually causes more problems than it solves. A single DLL dropped into a folder isn't registered the same way and skips the other supporting files the redistributable installs alongside it.



Which Programs Commonly Trigger This Error


Games launched through Steam or Epic Games, Microsoft Office applications, and other software built with Visual Studio's 2015 to 2019 C++ runtimes are the most frequently reported triggers. 


Steam alone accounts for roughly three-quarters of PC digital game distribution, according to data from Statista, which is part of why Steam-launched titles turn up so often in these reports.



Conclusion


The vcruntime140_1.dll error is almost always fixed by installing the official 64-bit Visual C++ Redistributable, not by downloading the DLL alone. 


Reinstalling the affected program and restarting afterward usually finishes the job.


FAQ


What causes the vcruntime140_1.dll error?


Most often a missing, corrupted, or wrong-architecture Visual C++ Redistributable. An incomplete program install can cause the same symptom.


Is it safe to download vcruntime140_1.dll on its own?


It's generally discouraged. A standalone file isn't registered or matched to your system the way the official installer handles it.


Do I need the x86 or x64 version?


This file requires the 64-bit (x64) redistributable. The 32-bit (x86) package doesn't include it.


Does reinstalling the affected program fix it by itself?


Sometimes, if the redistributable is already installed correctly. If not, reinstalling the program alone usually won't help.


What if the error still shows up after reinstalling the Redistributable?


Uninstall it completely, restart, then install it again. A repair install skips this step and sometimes isn't enough.
