Microsoft Visual C 2010 Redistributable Package X64 _best_ May 2026

Here’s a clear, informative text about the Microsoft Visual C++ 2010 Redistributable Package (x64) , suitable for a FAQ, software documentation, or support page.

Official Microsoft Download Centers

The legitimate Microsoft Visual C++ 2010 Redistributable Package (x64) can be downloaded from:

  1. Microsoft Official Download Center (older direct link):
    https://www.microsoft.com/en-us/download/details.aspx?id=14632 microsoft visual c 2010 redistributable package x64

    • Look for file: vcredist_x64.exe

    Search for "Visual C++ 2010 Redistributable x64"

  3. Visual Studio 2010 (SP1) Redistributable
    Service Pack 1 version includes security and reliability fixes. Highly recommended. Here’s a clear, informative text about the Microsoft

    • Search: KB2467173 – Security Update for Visual C++ 2010 SP1 Redistributable.

Security considerations

  • The CRT has had vulnerabilities over time; use SP1 and apply all security updates from Windows Update.
  • Avoid downloading from untrusted sites — use official Microsoft download sources.

Versions and servicing

  • Main releases: original RTM, SP1 (service pack 1). SP1 is the recommended version for security and bug fixes.
  • Different installers exist for x86 and x64; x64 package provides 64-bit runtimes for 64-bit apps, but 32-bit apps on x64 Windows still require the x86 redistributable.
  • Side-by-side (SxS) installation: multiple VC++ redistributable versions can coexist because each version installs versioned SxS assemblies in the WinSxS folder using manifests.

Q4: Why does the installer say "Command line option syntax error"?

A: You might have used incorrect switches. For silent install, ensure you use /quiet not -quiet. Also, run from a short path (e.g., C:\temp\).

Core Features

  1. Runtime DLLs – Installs essential 64-bit runtime libraries: run from a short path (e.g.

    • Microsoft C Runtime (MSVCR100.dll)
    • Microsoft C++ Runtime (MSVCP100.dll)
    • OpenMP (VCOMP100.dll)

  2. MFC Libraries – Microsoft Foundation Classes for 64-bit applications

  3. ATL Libraries – Active Template Library for COM components

  4. C++ Standard Library – Standard template library (STL) implementation

The End-of-Life Risk

Because extended support has ended, it is technically insecure to continue relying on the VS 2010 redistributable in mission-critical environments, especially those connected to the internet. If you cannot recompile against a newer runtime, you must:

  • Isolate the application in a virtual machine.
  • Harden your firewall to limit network exposure.
  • Monitor for known CVEs related to msvcr100.dll.
