Hololens 2 Emulator HRESULT: 0x80070005 (E_ACCESSDENIED)

Question

Hololens 2 Emulator HRESULT: 0x80070005 (E_ACCESSDENIED)

BR14Nx 15

I am trying to run the Hololens 2 Emulator on Windows 11 Pro.

All Windows Updates are installed.

Hyper-V is enabled and running.

My GPU, CPU and RAM are definitely sufficient.

Running the Emulator as Administrator is working without any problem, though it is still not working if I deploy a program from Visual Studio 2019 to the Emulator (Release and x86). Launching Visual Studio as Administrator does not work either. I get the same result. Launching the Emulator as Administrator before the deployment also does not work since a new VM will be started. Following this does not help either. I neither do not know what the SID of the VM is (since there is no "Details" button) nor what the ":(F)" stands for (which gives a CommandNotFoundException).

The error message of the emulator is as follows:

[XDE:002] The emulator is unable to verify that the virtual machine is running:

Access denied (Exception of HRESULT: 0x80070005 (E_ACCESSDENIED))

All the suggestions mentioned here did not work either or were not possible.

I also repaired Visual Studio 2019 and reinstalled the Emulator two times.

Hello, Welcome to Microsoft Q&A,

What are the exact versions of Windows and the HoloLens 2 Emulator? Have you tried deleting all files in %localappdata%\Microsoft\XDE\HCS? For this error message, there is a known issue for your reference - visual studio 2022 - HoloLens 2 "emulator unable to verify that the virtual machine is running. access is denied" error - Stack Overflow. And it is recommended to use Visual Studio 2022 to do some tests - Install the tools - Mixed Reality | Microsoft Learn.

Also, you can install the application via Device Portal. Please refer to Packaging MSIX apps - MSIX | Microsoft Learn to package the application and then refer to Using the Windows Device Portal - Mixed Reality | Microsoft Learn to install.

@Zuocheng Wang - MSFT I already tried to delete the .json's in the HCS folder, but with no luck.

I am aware about the device portal installation, but how can I debug things, so I can read the logs live?

I just noticed that I can also deploy an app via remote computer onto a running emulator. Though the first deployment fails with 0x801c000E Acces Denied Exception. Trying it again like mentioned here was finally installing the application while debugging it in VS. Nevertheless the application is not really starting. I can only see an empty application window.

You can find the log file in Device Portal->System->File Explorer->User Folders->LocalAppData->[Your project name]->TempState. Also, please provide your windows version and Emulator version if possible so that we can further troubleshoot, and as I said above, you can try to use Visual Studio 2022.

I tried the same steps with Visual Studio 2022 and I got the same effects.

Though I figured out how to use the debugger.

First you have to start VS with admin rights and debug to the Hololens 2 emulator. The first time will give an exception in VS. Ignore that and try it again (without closing the emulator). Now it will install and run the application on the already running emulator.

-> that's basically the same result I get when running the emulator independently and build the project that remote computer (though I have no debugger running)

Nevertheless the application window is still black. I checked the logs and saw some missing libraries.

It tells me MicrosoftOpenXRPlugin and UnityOpenXR dll's are missing. data providers like IMixedRealitySpatialAwarenessObserver and IMixedRealityInputDeviceManager are unregistered too.

But in the Mixed Reality Feature Tool I can see that I installed Mixed Reality OpenXR Plugin (Version 1.3.1). Also Unity OpenXR ist installed (Version 1.3.1). OpenXR is also used in the XR Plug-in Management with the Microsoft HoloLens feature group.

"Holographic Remoting remote app feature group" is not checked. Is that maybe necessary?

I am using the

MRTK 2.8.3 version

Windows 11 Pro 22H2

Hololens 2 Emulator 10.0.20348.1535

Please try to update the Mixed Reality Open XR Plugin to the latest version.

Can you share the detailed steps to build this project? If possible, please also provide an MCVE for us to test.

I updated Mixed Reality Open XR Plugin to 1.7.0, but still the same issue.

I build the project like this:

Setup project with those steps.

Build the project to Hololens as target device with x86, D3D, Release and the latest installed SDK Version. Minimum Platform Version is 10.0.10240.0 as recommended.

.vsconfig.txt -> my VS config. Am I maybe missing some older .net components? I removed some "out of support" components.

I run the emulator and VS as described above and open the projects .sln

I debug in Release and x86 to the target device via Remote Computer.

Installation is succesfull, but I get missing plugins in the logs as soon as I run it

In the logs I can even see some Debug outputs from my application in the end. So apparently it is starting, but the window still is empty:

I noticed the first issue in the logs is the OpenXR Plugin:

Plugins: Failed to load 'UnityOpenXR.dll' because one or more of its dependencies could not be loaded.

After that I get the other issues as described above.

Though I installed that Plugin in Unity. I removed it from the XR-Plugin Management and inserted it again. I tried to reinstall the Plugin in the Package Manager, though when I click "Remove" it still shows me that it is installed and I can "Remove" it. Is MRTK automatically downloading the plugin again?

I want to add that the whole project runs without any isssues on the real Hololens 2.

Thanks for the details and glad to hear that you the solution working well on the actual HoloLens 2 device. Also, good to hear running emulator as administrator is allowing this to start up at least.

For the scenario, is there a reason why sticking with x86?

For this one, is it possible to build x64 for emulator? Reason being the x86 was supposed to be primarily for HoloLens 1 development and new development would be using the newer tools targetting either x64 for the emulator or ARM64 for the device.

I just built to x64 and it is working now (after several installation attempts)

Documentation says Hololens 2 simulator can be build to via x86 and x64 though.
