While not always required, rebooting ensures that all newly installed DLLs are properly registered.
Here’s where most online advice gets outdated. The Visual C++ 2015, 2017, 2019, and 2022 redistributables are all binary-compatible with each other.
Microsoft now uses a single, unified runtime package that supports all of those years. In practice:
When an application (especially a game or a professional graphics tool like Adobe Photoshop or AutoCAD) fails to launch with a missing DLL error, follow these steps:
Step 1: Identify the missing DLL name.
Step 2: Download the official package. Always obtain redistributables directly from Microsoft. The official URL is aka.ms/vs/17/release/vc_redist.x64.exe. (Note: Microsoft now distributes a combined package for Visual Studio 2015, 2017, 2019, and 2022 – all use version 14.x runtime).
Step 3: Repair or Reinstall.
Step 4: Clean up conflicting versions. Use Microsoft's Program Install and Uninstall Troubleshooter (formerly Microsoft Fix It) or a tool like Geek Uninstaller to remove all versions of Visual C++ 2015-2022 Redistributable (both x86 and x64) from the “Add or Remove Programs” list. Then reinstall the latest version.
Step 5: Check system file integrity. Run sfc /scannow in an elevated Command Prompt. If the UCRT is part of the OS and has been damaged, this may restore it. microsoft visual c 2015 redistributable x64
Step 6: Inspect application event logs. Go to Event Viewer → Windows Logs → Application. Look for errors from source “SideBySide” or “Application Error” at the time of the failure. The error message often contains the exact version and path of the missing DLL, which can guide you further.
Developers who code in C or C++ using Visual Studio 2015 compile their code against these libraries. End-users must have the Redistributable installed to run that compiled software.
When a developer writes a program in C++ using Microsoft Visual Studio 2015, they rely on a set of standard libraries (DLL files). Instead of embedding those libraries into every single small program (which would waste disk space and memory), Microsoft allows developers to distribute the runtime components separately. These are the “redistributables.”
Let’s clarify one major point of confusion: binary compatibility. While not always required, rebooting ensures that all
Starting with Visual C++ 2015 version 14.0, Microsoft made a commitment: any application built with version 14.0 (2015), 14.1 (2017), 14.2 (2019), or 14.3 (2022) can run on the same redistributable package—specifically, the latest update.
That’s why Microsoft now offers a combined installer:
