However, Possibly. As noted earlier, old installers for VulkanRT can pile up. If you uninstall a game, the VulkanRT installer it left behind remains. You can safely uninstall very old versions (e.g., 1.0.x) if you have a newer version (1.3.x) installed. But keeping the 1.1.1080 version is harmless; it takes up roughly 25 MB of disk space.

No. If you remove it, games or programs that rely on the Vulkan API will crash or fail to launch.

This usually happens due to Windows File Protection. Run the installer as an Administrator (Right-click -> Run as administrator). If that fails, disable Windows User Account Control (UAC) temporarily, install, then re-enable it.
