Understanding "vc2013redistx86": Why You Need It and How to Install It Safely

If you are seeing an error message referencing "vc2013redistx86", "Visual C++ 2013 x86", or a version number like 120.40664, it usually means you are trying to run a specific Windows application or game, but a required system component is missing or corrupted.

This post explains what this file is, why version numbers matter, and how to fix the error safely.

Is vc2013redistx86 Safe? Security Considerations

Yes, the official package from Microsoft Update Catalog or Microsoft Download Center is safe. However, beware of third-party “DLL download” sites that offer msvcr120.dll individually. These files may be:

Always verify the digital signature:

Since version 12.0.40664 includes security patches for CVE-2017-11824 and other RCE vulnerabilities, using old builds is a significant risk—especially in server environments.

Silent Deployment for System Administrators

For IT professionals managing dozens of workstations, use the following script to check for and deploy missing 12.0.40664:

@echo off
reg query "HKLM\SOFTWARE\Microsoft\VisualStudio\12.0\VC\Runtimes\x86" /v Bld | find "40664"
if %errorlevel% == 0 (
    echo Correct version already installed.
    exit /b 0
) else (
    echo Installing vc2013redistx86 12.0.40664...
    vcredist_x86.exe /quiet /norestart
)

For offline systems, download the redistributable from the Microsoft Update Catalog (search for KB3134231 or KB3179560).

Understanding VC2013Redist_x86: A Guide to Visual C++ 2013 Redistributable (12.0.40664)

If you’ve ever tried to launch a game or a professional software application only to be met with an error like "MSVCP120.dll is missing" or "The application failed to start because its side-by-side configuration is incorrect," you have encountered a missing runtime dependency.

Specifically, VC2013Redist_x86 (version 12.0.40664) is one of the most common requirements for Windows software developed using Microsoft Visual Studio 2013. Here is everything you need to know about what it is, why you need it, and how to fix errors related to it. What is VC2013Redist_x86?

The Visual C++ Redistributable Packages install runtime components that are required to run C++ applications built using Visual Studio.

VC2013: Refers to the version of the compiler (Visual Studio 2013).

Redist: Short for "Redistributable," meaning it is a package developers can distribute to end-users so their programs work on any machine. Understanding "vc2013redistx86": Why You Need It and How

x86: This indicates the 32-bit version. Even if you are on a 64-bit version of Windows, you often need the x86 version because many applications are still built as 32-bit processes.

12.0.40664: This is the specific build number. It represents an update to the original 2013 release, often containing security patches and stability improvements. Why Do You Need It?

Software isn't just one giant file. Developers use "libraries" (pre-written code) to handle basic tasks like displaying windows, managing memory, or processing graphics. Instead of including these massive libraries inside every single app, Windows uses shared files called DLLs (Dynamic Link Libraries).

If a program was built using the 2013 version of Visual C++, it looks for the 12.0 version of these libraries. If they aren't on your system, the program won't run. Common Errors Solved by this Package

Installing or repairing version 12.0.40664 typically resolves the following:

"The program can't start because MSVCR120.dll is missing from your computer." "The program can't start because MSVCP120.dll is missing." "Runtime Error! Program: C:..." "0xc000007b" error codes during application launch. How to Install VC2013Redist_x86 (12.0.40664) 1. Check your current versions

Before downloading anything, go to Control Panel > Programs and Features. Scroll down to "Microsoft Visual C++ 2013 Redistributable." If you see version 12.0.40664 listed but are still getting errors, you may need to Repair it. 2. Download from Official Sources

Always download these packages directly from Microsoft to avoid malware. Visit the official Microsoft Download Center.

Search for "Visual C++ Redistributable Packages for Visual Studio 2013." Select the vcredist_x86.exe file. 3. Installation Tip for 64-bit Users

If you are running a 64-bit (x64) version of Windows, it is highly recommended to install both the x86 and the x64 versions. Many 64-bit programs still utilize 32-bit sub-processes, and having both ensures maximum compatibility. Trouble Shooting: Still getting errors? If you have installed the package but the error persists:

Restart your computer: Many DLL registrations require a reboot to finalize.

Reinstall the Application: The software itself might be looking for the DLL in its own local folder rather than the System32 folder. Outdated (leading to crashes) Infected with malware Missing

Run Windows Update: Sometimes, a pending Windows update can block the proper registration of C++ libraries.

Summary: vc2013redistx86 is a vital "bridge" between your hardware and the software you want to use. Keeping version 12.0.40664 installed ensures that older, stable applications and games continue to run smoothly on modern versions of Windows.
