Version 1.0.39.1: This specific version is an older, stable release from around 2017. While newer versions exist, this one is still functional for the software that installed it. Released in late 2016 / early 2017 –

Developed by the Khronos Group—the same non-profit consortium behind OpenGL—Vulkan was designed to provide better performance and more efficient CPU/GPU usage compared to older standards. Version 1.0.39.1 is a specific release of the "Runtime," which refers to the set of files (specifically vulkan-1.dll) required for games to actually run the Vulkan API on your system. Why Is It on Your Computer?

The "Runtime Libraries" are the system files that let Vulkan-based applications run on your PC. Without them, any game or program that uses Vulkan would crash or refuse to launch.

Issue: Vulkaninfo shows “Failed to create Vulkan instance”

Cause: Your GPU does not support Vulkan, or the driver is corrupted.

The "Passive" Method: When you install a new game or update your GPU drivers, they usually install a newer version of the Vulkan Runtime automatically.
The "Clean" Method: If you are a stickler for system cleanliness, you can uninstall old versions (like 1.0.39.1) and simply download the latest Vulkan Runtime Installer directly from the LunarG website. This will install the newest version and satisfy the requirements of all your older games.
