This article is for users who experience problems when they install Visual C++ Runtime components by using the Visual Studio Installer or the Visual C++ Redistributable (VC Redist) installer. If you experience any problems, make sure that you're installing the latest version of the Visual C++ Redistributable . Collect failure logs The first step to diagnose a problem with the Visual C++ Redistributable installer is to collect its failure logs. Download the Microsoft Visual Studio and .NET Log Collection Tool . Run Collect.exe . Extract the contents of %TEMP%/vscollect.zip . After you extract vscollect.zip , the VC Redist logs are located inside the Temp folder. The relevant log files are prefixed with the pattern dd_vcredist_<arch>_yyyyMMddHHmmss . Search the VC Redist logs for terms like "Error," "Failed," or "System Error," and consult the Common errors at a glance section to identify the problem. Other log locations The VC Redist installer is often run as a prerequisite of other products. In such cases, you might find the installation log in a different path. For example, Configuration Manager upgrades VC Redist as part of its own upgrade process by running vcredist_x64.exe with the /l option that overrides the default log location. In such cases, you can find the path to the logs by reading that product's own logs. Example: Configuration Manager logs <ConfigMgr_Installation_Directory>\Logs\cmupdate.log General troubleshooting steps when using the Visual C++ Redistributable installer This section describes general troubleshooting methods that you can try to resolve problems with the VC Redist installer. Disable antivirus software temporarily Antivirus software often blocks installation of VC Redist components. Turn off Windows Defender real-time protection. Disable any corporate endpoint protection temporarily (such as Symantec or McAfee). Retry the installation. Reenable any disabled protection software. Reenable any disabled protection software after you finish these steps. Run the Visual C++ Redistributable installer as administrator File-access failures are heavily correlated with insufficient permissions.

Common problems Common errors at a glance Generic installation failure (return code 1603) Access denied (return code 5) File is locked (return code 32) Corrupt or invalid installer package (return code 1620) Older version can't be removed (return code 1714)

Generic installation failure Return code 1603 indicates a generic installation failure produced by the Windows Installer during the installation of the Visual C++ Runtime components. Because many factors can produce a 1603 code, the code by itself doesn't provide enough information to diagnose the cause of the problem. Often, the log files produced by the VC Redist installer contain relevant information that might lead to a solution or workaround. The Common problems section describes examples of how to diagnose common installation errors and steps that might resolve them.
