Version History and Update Details
Microsoft released multiple updates to the Visual C++ 2015 runtime after the initial launch, addressing bugs, security issues, and compatibility improvements. Tracking build numbers and associated Knowledge Base articles helps with troubleshooting and verifying installed versions.
For x64 systems, both the initial package and subsequent servicing stack updates must be present for optimal stability. Below is a concise version timeline for common reference.
| Package Version | Build Number | Release Date | Associated Update |
|---|---|---|---|
| 14.0.23026 | v14.0.23026 | July 2015 | Initial Release |
| 14.0.23506 | v14.0.23506 | November 2015 | Security update rollup |
| 14.0.24210 | v14.0.24210 | March 2016 | Update for compatibility |
| 14.0.24215 | v14.0.24215 | April 2016 | Stable baseline for x64 |
| 14.0.24215.1 | v14.0.24215.1 | Later servicing | Included in Windows Update |
| 14.16.27029 | v14.16.x | 2018–2019 | Visual Studio 2017 merge updates |
Compatibility and Dependency Considerations
Applications built with Visual Studio 2015 often depend on specific C++ runtime features, and the x64 redistributable provides these components for 64-bit processes. Conflicts can occur when multiple versions of the Visual C++ runtime are present, so reviewing installed programs and ensuring consistent updates is recommended.
Verify that application documentation lists the Microsoft Visual C++ 2015 Redistributable Package (x64) as a prerequisite. Some installers bundle the runtime, while others require manual installation to satisfy dependencies.
Troubleshooting Common Issues
Runtime errors such as missing vcruntime140.dll or msvcp140.dll typically indicate that the Visual C++ 2015 redistributable is not correctly installed. Reinstalling the package using the official vc_redist.x64.exe from Microsoft usually resolves these issues.
If conflicts arise with other Visual C++ versions, install the latest servicing stack updates for Visual Studio 2015 and apply relevant Windows updates. Event Viewer logs and application error messages can help pinpoint missing dependencies or registration problems.
Recommendations and Best Practices
- Download the Visual C++ 2015 Redistributable Package (x64) only from official Microsoft sources to avoid tampered versions.
- Deploy the package silently using msiexec or your endpoint management tool in enterprise environments.
- Keep the package updated by enabling Automatic Updates or periodically checking the Microsoft Update Catalog.
- Verify application compatibility by consulting the vendor’s documentation for required Visual C++ runtime versions.
- Before removing older runtimes, confirm that no critical applications depend on them to prevent unexpected failures.
FAQ
Reader questions
Is the Microsoft Visual C++ 2015 Redistributable Package (x64) safe to install even if I already have newer Visual C++ runtimes?
Yes, it is safe. Installing the 2015 runtime alongside newer versions allows older applications to access their required libraries without interfering with updated runtime components used by other software.
Can I uninstall older versions after installing the latest update for Visual C++ 2015 Redistributable (x64)?
Check application support requirements before removing older versions. Some programs specifically require the 2015 runtime build, and uninstalling it may cause those applications to fail until the correct version is restored.
What should I do if a 64-bit application fails to start because of a missing DLL from the Visual C++ 2015 runtime?
Download and run the official vc_redist.x64.exe installer from Microsoft to repair or install the missing components. If the issue persists, run Windows Update to apply the latest servicing stack updates for this package.
Are there any performance implications when installing multiple Visual C++ redistributable packages on the same system?
Performance impact is minimal, as the runtimes primarily provide libraries and do not consume significant resources. Keeping them updated ensures security patches and compatibility fixes that support overall system stability.
