Microsoft Visual C 2010 Redistributable Package X64 [top] May 2026
The Unsung Hero of Windows: Understanding the Microsoft Visual C++ 2010 Redistributable (x64)
If you have ever peeked at your Windows "Installed Programs" list, you have likely seen a long, confusing list of entries titled Microsoft Visual C++ Redistributable . Among them, the version often stands out as a staple.
While it might look like clutter, this package is a critical bridge between your hardware and the software you use every day. Here is a deep dive into what it is, why it is still on your machine, and whether you should touch it. What Is It, Exactly?
The Microsoft Visual C++ 2010 Redistributable Package (x64) installs the runtime components of Visual C++ libraries.
Think of it this way: developers use a "toolbox" (Visual Studio 2010) to build apps. To save space, they don't include every single tool in the final app. Instead, they rely on your computer to have a shared "toolbox" already installed. This "redistributable" is that shared toolbox for any 64-bit app built with the 2010 version of Microsoft’s compiler.

Even as we move toward newer versions of Windows and Visual Studio, the 2010 Redistributable remains essential for several reasons: Legacy Software Support : Many classic games, older versions of Adobe Dreamweaver , and enterprise tools like JD Edwards EnterpriseOne rely specifically on the 2010 runtime. No Modern Replacement
: Unlike the 2015–2022 versions, which are "binary compatible" and can be updated by a single newer package, older versions like 2010 are unique. You cannot replace the 2010 version with the 2022 version; they are incompatible. Safety in Architecture
: The "x64" specifically services 64-bit applications. You might even see an "x86" version next to it; these serve 32-bit apps and are both necessary if you run a mix of software. Common "Runtime Error" Fixes If you see a popup saying a file is missing (like msvcr100.dll ), it usually means this package is corrupt or missing.
The Core Concept
To understand the redistributable package, you first need to understand Microsoft Visual C++ (MSVC) . This is Microsoft’s integrated development environment (IDE) used by millions of developers to write applications in C, C++, and C++/CLI. The Unsung Hero of Windows: Understanding the Microsoft
When a developer writes a program in C++, they rely on a set of pre-built code libraries—known as the C++ Runtime Library. These libraries handle basic functions like memory management, input/output operations, string manipulation, and mathematical calculations.
In the past, every developer used to bundle these libraries directly into their program’s installation folder. This led to massive file sizes, wasted disk space, and potential conflicts if multiple programs used different versions of the same library.

Part 5: How to Download the Official and Safe Version
Because the microsoft visual c 2010 redistributable package x64 is so popular, many third-party sites offer "downloads" that are actually malicious software, adware, or outdated versions. Always download directly from Microsoft.
Part 9: Security Considerations and Updates
The original Visual C++ 2010 Redistributable (without service packs) has known vulnerabilities, including DLL hijacking risks and remote code execution flaws. Always install the SP1 version plus the security update KB2467173. The Core Concept To understand the redistributable package,
To check if you have the secure version:
- Look for 10.0.40219.325 or higher in Programs and Features.
- Alternatively, check the file properties of
msvcr100.dllinC:\Windows\System32(for x64). The file version should be at least10.0.40219.325.
Microsoft ended mainstream support for Visual C++ 2010 in 2015, but extended support ended in 2020. That means no new security patches. For mission-critical systems, consider isolating legacy apps in virtual machines.
Error 1935 – Installation corrupt
This indicates a Windows Installer or .NET Framework corruption.
- Run
sfc /scannowin an elevated command prompt. - Use Microsoft’s System Update Readiness Tool (for older OS).
The Verdict
For the vast majority of Windows users, the answer is yes. The Microsoft Visual C++ 2010 Redistributable Package (x64) is a safe, lightweight, and essential component that enables thousands of 64-bit applications and games to function correctly.
Install it if:
- You play classic PC games from 2010–2015.
- You use professional software released in that same era.
- You encounter "missing MSVCR100.dll" or "missing MSVCP100.dll" errors.
Do not install it if:
- You are running a 32-bit Windows OS (install the x86 version).
- You are certain that none of your installed software requires it (rare).
- Your security policy prohibits out-of-support Microsoft components.
