What is this error?
The Vulkan runtime DLL is missing from your system. Games requiring Vulkan cannot start without this file.
Common causes
- GPU driver doesn't include Vulkan runtime
- Vulkan runtime was removed or corrupted
- antivirus quarantined the DLL
- very old GPU driver without Vulkan support
How to fix it
- Update GPU driver (includes Vulkan runtime)
- install Vulkan Runtime separately if needed

"vulkan-1.dll was not found" means the Vulkan runtime library isn't installed. Unlike DirectX, Vulkan is installed by your GPU driver — if you have an old driver or a clean Windows install, it may be missing.
This blocks games like Doom Eternal, Baldur's Gate 3, X-Plane, and emulators like RPCS3 and Yuzu/Ryujinx.
How to fix it:
- Update your GPU driver from NVIDIA, AMD, or Intel's website — the latest driver installs vulkan-1.dll automatically
- If updating the driver doesn't fix it, download and install the Vulkan Runtime from the LunarG Vulkan SDK page
- Check if vulkan-1.dll exists in C:\Windows\System32\ (64-bit) and C:\Windows\SysWOW64\ (32-bit) — it should be in both
- Check your antivirus quarantine — some antivirus software flags vulkan-1.dll as suspicious
- If your GPU is very old and doesn't support Vulkan at all, you'll need to use a DirectX version of the game if available
- Never download vulkan-1.dll from random DLL websites — always install it via the GPU driver or official Vulkan SDK
