Vulkan-1 Dll Not Found

[Rell Jette]

And the emulator is not opening. I've uninstalled the current version (4.1.1) and installed 4.0.1 of Android Studio, but problem is not solved. Now I'm in the latest version of Android Studio i.e., 4.1.1.

I got the same error yesterday, when I installed the latest version of Android Studio (4.2.2 on the stable channel). Every time I tried to start an Emulator I got a warning saying that "The emulator process for AVD was killed", after looking the IDE's Log, I found this:

I have the above directory structure for the SDK and I have a folder for the vulkan drivers as you can see above. I was able to copy the file: vk_swiftshader.dll to the parent lib64 directory, rename it to vulkan-1.dll to solve the problem

I have encountered the same problem where emulator.exe ended abruptly with the same lines on the console. After hours of experiment, downgrading the emulator version from Android Emulator 3.7.5 to 30.4.5.0 (build_id 7140946) worked.

I don't think this should be the error vulkan-1.dll is the reason for the process to end abruptly. I am saying this because my logs from a successful run on 30.4.5.0 (build_id 7140946) also showing this dll missing error but continued and the emulator showed up successfully.

In my case this happened after I installed Visual Studio Code. And the error log isWARN - Emulator: Pixel 4 API 30 - Please update the emulator to one that supports the feature(s): Vulkan,
So I've just updated the emulator Graphics setting to Software:

I tried a lot of suggested solutions, mainly from stack overflow, and nothing worked. For context, I'm using Windows 10 Pro [Version 10.0.19045.3803]. I want to share this solution because it might work for some, and for the future me just in case I get this problem again.

It only happened because I fiddled with the OpenGL ES Renderer and OpenGL ES API level settings in the Extended Controls of the current Android Studio emulator session. I hope that it would fix the rendering problem of missing texts during my debugging sessions.

Judging from a lot of solutions, it seems re-assigning the said settings above in a roundabout way would fix it. However, none of those solutions worked for me, so I tried reinstalling android studio and cleaning up its residues manually and yet to no avail.

So, at my wits end, I thought that maybe it stores settings in registry. Because how it would retain the settings after all that? Then, I sought for and found a setting in registry that is highly likely related to the problem at hand and modified its keys. I did make a backup beforehand though, but that's another guide.

Till yesterday it was fine. But today while launching the overwatch game in Vulkan mode, I got an error saying that Vulkan-1.dll was not found. AMD Radeon RX 5600 XT is the graphics card that I have on my PC. I re-installed it but that didn't work for me. Kindly provide me some solutions. Thanks in advance.

I searched on google and found a solution to download the latest version of Vulkan-1.dll and I did exactly that. Thus, I downloaded the DLL file from this link: -1-dll/ . But, this also didn't fix my issue. Any more help on this. Thanks.

Errors related to vulkan-1.dll can arise for a few different different reasons. For instance, a faulty application, vulkan-1.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry.

In the vast majority of cases, the solution is to properly reinstall vulkan-1.dll on your PC, to the Windows system folder. Alternatively, some programs, notably PC games, require that the DLL file is placed in the game/application installation folder.

I have experienced the problem when using Xamarin in Visual Studio. My operating system is Windows 10 working on MacBook BootCamp. Firstly, I got warning to enable Hyper-V or HAXM accelerators. As much as I understood, Hyper-V is Windows operation system's virtual machine accelerator while HAXM is Intel's microcontroller scope virtual machine accelerator. It was saying prefer Hyper-V when available over HAXM in the documents. So I tried to enable it (hardware-acceleration).

To check what are needed to enable it, in the terminal (cmd), entering "systeminfo" command lists requirements. My only need was "Virtualization Enabled in Firmware: No". I searched a little and found a Stackoverflow solution saying starting on MacOS and then go to System Preferences > Startup Disk and restart into Windows operating disk partition and it worked! Then when entering "systeminfo" command "Hyper-v": "Virtualization Enabled in Firmware" turned to "Yes", all others requirements were already yes.

At this stage it is also needed to turn Hyper-V Windows Features on, it can be handled by searching for "Turn Windows Feature On and Off. After setting related features on Windows needs restart, then when I type "systeminfo" again it displayed "Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed.":

I was happy, everything is done! I created emulator and try to start but it sucks. This "vulkan-1.dll" and "Try hwr.gpu.mode = off" errors occured. Thankfully, I see this post and solution of @Young Calabria , then all nightmares are ended.

By the way, these are my ".android" folder and "advancedFeatures.ini" files. ".android" folder is placed in root folder of the current Windows user together with "Desktop", "Document", etc. folders. In my "advancedFeatures.ini" file, there was a line "WindowsHypervisorPlatform=on", I haven't deleted that also. This settings make it work.

So it's looking like I'll have to start trying to toy around with vulkan and at least get things working to where I can understand it at a high level. I was wondering if there was any general advice, good tutorials/information you've found, or things to watch out (any major gotchas) for when starting with it, based on your experience.

I learned from vulkan-tutorial.com, which is the most popular one around. It's in modern C++ and has complexity issues -- here are the gotchas you should be aware of. There's currently no better place to learn the API though.

Thanks for your input. After skimming through the vulkan-tutorial.com website it states that the SDK makes debugging easier and without it you can have a lot more driver crashes and situations where you do not know why things aren't working. Do you experience difficulty with this? Do you think the SDK would be helpful in this area? As far as I can tell you can use the SDK with plain c as well, even though the tutorial website uses c++ concepts.

SDK gives prebuilt/ready to use validation layer binary. Which is very very useful. You should always use API validation layer during development - this applies to other GPU api like OpenGL and D3D11/12 too. They help a lot for you to diagnose and debug issues related to wrong api usage.

Vulkan SDK also gives glsl to spirv compiler. So you can precompile all shaders you ship in your application. Technically you can build it from source yourself, or even ship with your application, but meh.. why bother if they already give you binary to use.

Within the SDK if I look into the includes folder it lists headers for the extra stuff like the shader compiler (dxc) and spirv conversion (spirv_cross) but the actual vulkan specification headers are found in the vulkan/vk_video folders. After including the vulkan headers in my app, I make sure to link to the vulkan-1.lib found within the SDK's lib folder. This lib is an import library that knows where the standard installs of the vulkan-1.dll's are (which are your graphics card's vulkan drivers that have been downloaded at some point). Depending on the vulkan version your drivers support, you can use certain vulkan extensions which are called through the vulkan headers and loaded via the vulkan-1.lib file (assuming you're using the same version headers/.lib). If this understanding is correct, where does the vulkan loader come into play? Is that a part of the vulkan-1.lib file?

This guide is intended to fill the gaps between the official Vulkan resources and the rest of the GLFW documentation and is not a replacement for either. It assumes some familiarity with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to the Vulkan documentation to explain the details of Vulkan functions.

By default, GLFW will look for the Vulkan loader on demand at runtime via its standard name (vulkan-1.dll on Windows, libvulkan.so.1 on Linux and other Unix-like systems and libvulkan.1.dylib on macOS). This means that GLFW does not need to be linked against the loader. However, it also means that if you are using the static library form of the Vulkan loader GLFW will either fail to find it or (worse) use the wrong one.

macOS: To make your application be redistributable you will need to set up the application bundle according to the LunarG SDK documentation. This is explained in more detail in the SDK documentation for macOS.

If you are linking directly against the Vulkan loader then you can skip this section. The canonical desktop loader library exports all Vulkan core and Khronos extension functions, allowing them to be called directly.

This function in turn calls vkGetInstanceProcAddr. If that fails, the function falls back to a platform-specific query of the Vulkan loader (i.e. dlsym or GetProcAddress). If that also fails, the function returns NULL. For more information about vkGetInstanceProcAddr, see the Vulkan documentation.

Device-specific functions may execute a little faster, due to not having to dispatch internally based on the device passed to them. For more information about vkGetDeviceProcAddr, see the Vulkan documentation.

These extensions must all be enabled when creating instances that are going to be passed to glfwGetPhysicalDevicePresentationSupport and glfwCreateWindowSurface. The set of extensions will vary depending on platform and may also vary depending on graphics drivers and other factors.
