Understanding Microsoft Visual C++ 2015 Redistributable (x64)
If you’ve ever tried to launch a PC game or a professional software suite only to be met with an error message like "The program can't start because MSVCP140.dll is missing," you have encountered a missing Microsoft Visual C++ 2015 Redistributable.
While it sounds like a mouthful of technical jargon, it is one of the most essential components for any Windows-based system. Here is a clear breakdown of what it is, why you need the x64 version, and how to manage it. What is a "Redistributable"?
Software developers use "libraries" of pre-written code to perform common tasks so they don't have to reinvent the wheel for every program. Many Windows applications are written using Microsoft Visual C++.
When a developer finishes their app, they don't include all those massive code libraries inside the app’s folder (which would make every app huge). Instead, they rely on a "Redistributable" package. This is a centralized bundle of those libraries that lives on your operating system, allowing multiple different programs to "share" the same code. Why "x64"?
The x64 tag refers to the 64-bit architecture of your operating system.
x64: For 64-bit Windows. Most modern PCs built in the last decade run this. x86: For 32-bit Windows.
Pro Tip: Even if you have a 64-bit computer, you may still see the x86 version installed. This is normal; 32-bit applications still require the x86 libraries to run, even on a 64-bit system. Common Errors and Fixes
The most frequent reason people search for this keyword is a system error. The most common "symptoms" of a corrupted or missing 2015 Redistributable are: MSVCP140.dll is missing VCRUNTIME140.dll was not found The application was unable to start correctly (0xc000007b) How to Fix These Errors:
Repair the Installation: Go to Settings > Apps > Installed Apps. Find "Microsoft Visual C++ 2015 Redistributable (x64)," click the three dots (or right-click), select Modify, and then click Repair.
Clean Reinstall: If a repair fails, uninstall the package entirely. Then, visit the official Microsoft Download Center to download a fresh copy.
The 2015-2022 Bundle: Note that Microsoft now bundles the 2015, 2017, 2019, and 2022 versions into a single installer. Installing the latest "2015-2022" package will often resolve issues for all four versions simultaneously. Is it Safe to Delete?
You might see a dozen different versions of these Redistributables (2005, 2008, 2010, 2012, 2013, 2015) in your App list. Do not delete them to save space.
Each version is unique. An older game might specifically require the 2010 version, while a newer app needs the 2015 version. Deleting them will cause those programs to stop functioning immediately. They take up very little space and are best left alone unless you are troubleshooting a specific error.
Are you currently seeing a specific .dll error message when trying to open a program? microsoft visual c 2015 redistributable x64
Instead of hunting specifically for the 2015 version, it is best practice to download and install the latest supported Visual C++ Redistributable (currently Visual Studio 2022). This ensures you have the latest security updates and bug fixes while maintaining full compatibility with 2015 software.

Conclusion
The Microsoft Visual C++ 2015 Redistributable x64 package is an essential component for running applications developed with Visual C++ 2015 on 64-bit Windows operating systems. By providing the necessary runtime components, developers can ensure that their applications are compatible with a wide range of systems, reducing support issues and simplifying deployment. With its ease of installation and troubleshooting, the Microsoft Visual C++ 2015 Redistributable x64 package is a crucial tool for developers and users alike.
The Microsoft Visual C++ 2015 Redistributable (x64) is a package of shared library files (DLLs) required to run 64-bit applications developed with Visual Studio 2015. Without these libraries, many games and professional software packages will fail to launch, often returning errors like "MSVCP140.dll is missing". Core Purpose and Functionality
Run-time Components: It installs essential components for libraries such as C Runtime (CRT), Standard C++, MFC, C++ AMP, and OpenMP.
Dependency Management: Developers use these libraries to avoid rewriting common code (like math or file I/O functions) for every app. Instead, they link to these shared files.
Standalone Execution: It allows users to run C++ applications on systems that do not have the full Visual Studio development suite installed.
Version Specificity: While modern packages (2015–2022) are often cumulative and backward compatible, some older applications still specifically require the 2015 version. System Requirements
Visual C++ Redistributable for Visual Studio 2015 - Microsoft
The Microsoft Visual C++ 2015 Redistributable (x64) is a package of shared code libraries that allows your computer to run 64-bit applications developed using Visual Studio 2015.
When developers write software in C++, they often use "standard libraries" (pre-written code for common tasks like drawing windows or calculating math) instead of writing everything from scratch. For these programs to run on your PC, the corresponding libraries must be present. Key Functions and Benefits
Run-Time Components: Installs essential DLLs like the C Runtime (CRT), Standard C++, MFC, and OpenMP.
Application Portability: Enables you to run C++ apps even if the full Visual Studio development suite is not installed.
Shared Infrastructure: Multiple programs can use the same installed redistributable, saving disk space and ensuring consistency. Architectural Compatibility: x64 vs. x86 Recommendation Instead of hunting specifically for the 2015
For optimal system health, it is common to have both the x64 and x86 versions installed: x64 (64-bit): Required to run 64-bit applications.
x86 (32-bit): Required for 32-bit applications, even if you are on a 64-bit version of Windows.
Note: The x64 version does not cover dependencies for 32-bit programs, nor vice-versa. Important Maintenance Facts
Legacy vs. Modern Versions: The standalone 2015 version is technically "out of support," but Microsoft has replaced it with a unified 2015–2022 Redistributable. This newer package is binary-compatible and acts as a direct upgrade for the 2015 version.
Should You Uninstall It?: Generally, no. Removing it will likely cause any software that relies on it—such as games or CAD tools—to crash or fail to launch with errors like "MSVCP140.dll is missing".
Common Fixes: If you encounter installation errors (like code 1603 or "Setup Failed"), they are often caused by corrupted caches or existing newer versions already on the system. Repairing the installation via the Control Panel > Programs and Features is usually the safest first step.
What is Visual C++ Redistributable (2026 Guide How it Works)
The designation “2015” refers to the underlying version of the Visual C++ runtime library (version 14.0). This is crucial because runtime libraries are not always backward compatible. A program built with Visual Studio 2015 expects runtime version 14.0, not version 12.0 (from Visual Studio 2013).
The “x64” denotes the processor architecture. This particular package is for 64-bit (x86-64) systems. It contains 64-bit versions of the runtime DLLs, intended for 64-bit applications running on a 64-bit version of Windows. (The separate x86 version is for 32-bit applications, which run on both 32-bit and 64-bit Windows via emulation). A 64-bit application cannot use 32-bit DLLs, and vice versa, hence the need for architecture-specific redistributables.
Key files installed by this package (typically to C:\Windows\System32):
vcruntime140.dll – Core runtime functions (exception handling, startup/shutdown).vcruntime140_1.dll – Additional runtime (for newer C++ features in 2015 update 3).msvcp140.dll – C++ Standard Library (iostreams, containers, algorithms).ucrtbase.dll – The Universal C Runtime (UCRT), a shared system component introduced with Windows 10.Note on the Universal CRT: Starting with Visual Studio 2015, Microsoft restructured the runtime. The UCRT is now a Windows operating system component (Windows 10 and later have it built-in; Windows 7 and 8 receive it via Windows Update). This reduces the need for application-local copies but also creates unique compatibility scenarios across different Windows versions.
Many installations require replacing system DLLs. Close your browser, games, Office apps, and especially any developer tools (Visual Studio, Node.js, etc.).
The Microsoft Visual C++ 2015 Redistributable Package (x64) is a runtime component required to run applications developed with Microsoft Visual Studio 2015, specifically those written in C++ and compiled for 64-bit (x64) architecture.
In simple terms: if a developer uses Visual C++ tools to build a program, that program depends on a set of standard C++ libraries (like vcruntime140.dll and ucrtbase.dll). Instead of bundling these libraries into every single application (which wastes space and creates maintenance issues), Microsoft distributes them as a redistributable package. The end user must install this package once so that any 64-bit application requiring those files can run properly. Visual C++ 2015 Runtime Libraries : The package
The Microsoft Visual C 2015 Redistributable x64 is not just a “set and forget” component. Microsoft releases security updates for it through Windows Update.
