When you build an application that uses library DLLs supplied by Visual Studio, users of your application must also have those DLLs on their computers for the application to run. Because most users probably do not have Visual Studio installed, you must provide these DLLs for them. Visual Studio makes these DLLs available as redistributable files that you can include in your application installer.

Microsoft Visual C 2019 provides a powerful and flexible development environment for creating Microsoft Windows based and Microsoft.NET based applications. The Visual C Redistributable Package install run-time components of Visual C libraries. Download the Microsoft Visual C Redistributable for Visual Studio 2015, 2017 and 2019. The following updates are the latest supported Visual C redistributable packages for Visual Studio 2015, 2017 and 2019. Included is a baseline version of the Universal C Runtime see MSDN for details. X86: vcredist.x86.exe.

To make it easier to include the redistributable DLLs with your installer, they are available as stand-alone redistributable packages. These are architecture-specific executables that use central deployment to install the redistributable files on a user's computer. For example, vcredist_x86.exe installs the 32-bit libraries for both x86 and x64 computers, vcredist_x64.exe installs the 64-bit libraries for x64 computers, and vcredist_ARM.exe installs the libraries for ARM computers. We recommend central deployment because Microsoft can use the Windows Update service to independently update these libraries. In addition to the copy in your Visual Studio installation, the current redistributable packages are available for download. For links to the latest supported redistributable packages for both current and older toolsets, see The latest supported Visual C++ downloads. Specific earlier versions of the redistributable packages may be found by searching the Microsoft Download Center for 'Visual C++ Redistributable Packages'.

We only support using a redistributable package that's the same as or newer than your toolset version. The major version number of the redistributable package you deploy must match the version of the Visual Studio toolset used to create your application, and the minor version must be the same or higher. Visual Studio 2019, 2017 and 2015 all have compatible toolset version numbers, which means that newer Visual Studio redistributable files may be used by apps built by a toolset from an older version. For example, Visual Studio 2019 redistributable files may be used by apps built by using the Visual Studio 2017 or 2015 toolset. While they may be compatible, we don't support using older redistributable files in apps built by using a newer toolset. For example, using the 2017 redistributable files in apps built by using the 2019 toolset isn't supported.

Another way to include the redistributable DLLs with your installer is to use merge modules. These Microsoft Installer modules are included in and installed by your application installer. Merge modules for the redistributable DLLs are found in your Visual Studio installation directory under VCRedistMSVCversionMergeModules. In earlier versions of Visual Studio, these files are found in your Program Files or Program Files (x86) directory in a Common FilesMerge Modules subdirectory. For more information about use of these files, see Redistributing Components by using Merge Modules.

The individual redistributable DLLs are also included in your installation of Visual Studio. By default, they are installed in the Visual Studio installation directory in the VCRedistMSVCversion folder. The version numbers may represent different minor build numbers of a single common set of redistributable files. Use the latest version of any library DLL file, redistributable package, or merge module found in these directories. You may use these libraries for local deployment, by installing them in the same directory as your application. We don't recommend local deployment because it makes you responsible for delivering updates to your deployed applications. Central deployment by using the redistributable packages is preferred.

To determine which DLLs you have to redistribute with your application, collect a list of the DLLs that your application depends on. These are normally listed as import library inputs to the linker. Certain libraries, such as vcruntime and the Universal C Runtime Library (UCRT), are included by default. If your app or one of its dependencies uses LoadLibrary to dynamically load a DLL, that DLL may not be listed in the inputs to the linker. One way to collect the list of dynamically loaded DLLs is to run Dependency Walker (depends.exe) on your app, as described in Understanding the Dependencies of a Visual C++ Application. Unfortunately, this tool is outdated and may report that it can't find certain DLLs.

When you have the list of dependencies, compare it to the list linked in the Redist.txt file found under the Microsoft Visual Studio installation directory, or to the 'REDIST list' of redistributable DLLs that is referenced in the 'Distributable Code Files' section of the Microsoft Software License Terms for your copy of Visual Studio. For Visual Studio 2019, see Distributable Code for Visual Studio 2019. For Visual Studio 2017, see Distributable Code for Microsoft Visual Studio 2017 (Includes Utilities, Extensibility, and BuildServer Files). For Visual Studio 2015, see Distributable Code for Microsoft Visual Studio 2015 and Microsoft Visual Studio 2015 SDK (Includes Utilities and BuildServer Files). For Visual Studio 2013, the list is available online in Distributable Code for Microsoft Visual Studio 2013 and Microsoft Visual Studio 2013 SDK.

In Visual Studio versions before Visual Studio 2015, the C Runtime Library (CRT) was included as a redistributable DLL, in msvcversion.dll. Starting in Visual Studio 2015, the functions in the CRT were refactored into the vcruntime and the UCRT. The UCRT is now a system component in Windows 10, managed by Windows Update. It is available on all Windows 10 operating systems. To deploy your application to earlier operating systems, you may need to redistribute the UCRT as well. An early version of the UCRT is included in the Visual Studio redistributable files, which is only installed on operating systems earlier than Windows 10, and only if no version of the UCRT is already installed. For an installable version of the UCRT for downlevel systems as a Microsoft System Update package, see Windows 10 Universal C Runtime in the Microsoft Download Center.

You cannot redistribute all of the files that are included in Visual Studio; you are only permitted to redistribute the files that are specified in Redist.txt or the online 'REDIST list.' Debug versions of applications and the various Visual C++ debug DLLs are not redistributable. For more information, see Choosing a Deployment Method.

The following table describes some of the Visual C++ DLLs that your application might depend on.

Note

You no longer need to redistribute the Active Template Library as a separate DLL. Its functionality has been moved to headers and a static library.

For more information about how to redistribute these DLLs with your application, see Redistributing Visual C++ Files. For examples, see Deployment Examples.

Typically, you do not have to redistribute system DLLs because they are part of the operating system. However, there might be exceptions, for example, when your application will run on several versions of Microsoft operating systems. In this case, be sure to read the corresponding license terms. Also, try to get the system DLLs upgraded either through Windows Update, service packs or by using redistributable packages made available by Microsoft.

Software Applications

Overview

The Microsoft Visual C++ redistributable packages, also known as VCredist, are runtime components in support of Windows applications compiled with Microsoft Visual Studio. The x86 distributions are for 32-bit applications; the x64 versions are for 64-bit applications, regardless of the bitness of the operating system. The version needed depends on the version of Visual Studio that was used to compile the application, which should be specified in the application installation instructions:
