The Microsoft Visual C++ 2010 Redistributable Package (x64) is a collection of runtime components required to run 64-bit applications developed with Visual C++ 2010. These "shared libraries" allow programs to run on your PC even if you don't have the full Visual Studio development software installed. Why Is It on My Computer?
Automatic Installation: Most users find this on their system because a third-party application (like a game or utility) installed it automatically during its own setup.
Essential Functionality: If you uninstall it, programs that rely on its specific "MSVCR100.dll" or "MSVCP100.dll" files will stop working and show "missing DLL" errors.
No Conflicts: It is normal to have multiple versions (2005, 2010, 2015, etc.) installed simultaneously; different apps require specific versions to function. Download and Support Status
While Microsoft ended extended support for Visual Studio 2010 on July 14, 2020, you can still download the package for compatibility with older software.
Official Download: The Microsoft Download Center provides the Service Pack 1 (SP1) version, which includes critical security updates.
System Requirements: It supports Windows XP through Windows 11, though it was originally designed for Windows 7 and older Server editions.
Architecture: The x64 version is strictly for 64-bit applications. If an app is 32-bit (x86), you will need the x86 version regardless of your Windows version. Troubleshooting Common Errors
If you see "Runtime Error" or "MSVCP100.dll is missing," try these steps:
Repair the Installation: Instead of uninstalling, go to Settings > Apps, find the 2010 Redistributable, click Modify/Change, and select Repair.
Fresh Reinstall: If repairing fails, download a fresh copy from the Official Microsoft site and run the installer as an administrator.
All-in-One Packages: For users with many missing versions (common in gaming), community-vetted tools like the Visual C++ Redistributable Runtimes All-in-One can install all supported versions at once.

The Microsoft Visual C++ 2010 Redistributable Package (x64) is a collection of runtime library files required to run 64-bit applications developed with Visual C++ 2010. While it is an older package, it remains a critical component for many legacy games and professional software. Core Function & Purpose
Application Dependency: It acts as a bridge, providing pre-written code (libraries) that developers use so they don't have to write everything from scratch.
Runtime Components: Installs essential runtime components for C Runtime (CRT), Standard C++, ATL, MFC, and OpenMP.
x64 Architecture: Specifically supports 64-bit applications. If you have a 64-bit version of Windows, you likely have both this and the x86 (32-bit) version installed, as different programs require different architectures. Why Is It on Your Computer?
You likely didn't download this manually. It is typically installed automatically as a "prerequisite" when you install a piece of software—like an older game, a driver, or professional tools like Oracle JD Edwards. Safety & Maintenance Do I Need All These Microsoft Visual C++ Redistributables?
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. Why Is It Still on My PC in 2026? Why is the Microsoft Visual C++ 2010 Redistributable
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.
This happens when you try to install the same version. Solution:
You might think software from 2010 is obsolete. Not quite. Industries such as manufacturing, healthcare, finance, and academia still rely on legacy software. Examples include:
Even modern programs sometimes bundle older redistributables for backward compatibility. When you install a fresh copy of Windows 10 or 11, the 2010 x64 runtime is not pre-installed—you must install it manually or via the application installer.
When you successfully install the package, several critical dynamic link libraries (DLLs) are placed in your Windows system folders. For the x64 version, these are located in C:\Windows\System32 (not SysWOW64, which is for 32-bit files).
The primary files include:
msvcr100.dll – The C Runtime Library. Required for basic C functions like printf, malloc, and fopen.msvcp100.dll – The C++ Standard Library. Handles classes like std::string, std::vector, and iostreams.mfc100u.dll – The Microsoft Foundation Classes, used for building Windows desktop applications with menus, buttons, and dialogs.vcomp100.dll – The OpenMP library for multi-threading.mcrm100.dll – The C++ REST API (Casablanca) runtime for web services.If any of these files are missing, corrupted, or blocked by antivirus software, you will encounter runtime errors.
Before installing:
After installation:
If you continue to experience errors after a clean installation, run the Microsoft System File Checker (sfc /scannow), perform a malware scan, and consider using the Microsoft Visual C++ Redistributable Runtimes All-in-One package (from reputable sources like GitHub’s russellbanks/KBones), which bundles all versions to resolve conflicts.
