Hi,
I ve downloaded Skype via Microsoft Store, however i can not acces and immediately get an warning as "A problem occured signing into Skype, please try again later". Tried a few times and uninstall and install Skype but it is not working.

What would be the solution?

Thanks

I'm looking for a good offshore software development company, for Galaxy Explorer Project. Since the budget is limited, I consider working with foreign developers, any advice and recommendations will be extremely useful

I get error 0x803FB005 if I try to download, for example, skype.

Is it possible to track a different IR emitter than Windows MR controllers?
We are studying the possibility of tracking VR gloves with Windows MR devices.
Thanks.

Say I want to be a passenger in van going on a safari ride at a very low speed and I know the location of each of the animals. Could I mask the windows of the vehicle so the spatial mapping ignored the window and only mapped the frame?

Or could I place the interior of that van in the Hololens and have it lock onto the surrounding world with world anchors?

The headset is plugged into a 3.0 USB port on the back of my computer. The HDMI cable is plugged into my graphics card. The Windows Mixed Reality portal randomly started and told me the headset is working, I got excited and play the little tutorial mini game with the gems, then suddenly it got disconnected and no matter what I do I can't fix it. It was working before, I've done the setup multiple times, but the headset just randomly stops. Is there some requirement for the headset to count as connected?

The USB is snug in the slot, I've tried wiggling it slightly.
I've read the troubleshooting guide.
I can't find any help online.

There are 2 3.0 ports on my PC on the back and 2 in the front, but of course the cable for the HDMI and the USB are too short to reach the GPU while the USB is in the front. Does anyone have any suggestions to make this work?

Hello all, I'm working with Hololens and PhotonNetworking. I use the Mixed Reality Tookit within Unity. Everything work well in the editor, but after building the app with IL2CPP (because .NET generate some errors with photon). I built it the Visual Basic 2017 until here everything work well. When I get the deploying step I get the error bellow. I just show the unity logo and nothing else. I already try many option find in internet but nothing. I have test with Unity 2017.3.1f1, 2018.1.0b9 and 2018.2.0.b4, I get the same error. Help me please !

Hello,
I am trying to stream live video including holograms to a UWP App which runs on a PC. I do not want to use the REST API which is supported by the hololens natively since it has a 2 seconds delay. (I would use it for testing anyways, but I cant figure out how to receive the stream via http://172.22.111.82/api/holographic/stream/live_high.mp4?holo=true&pv=true&mic=false&loopback?holo=true&pv=true&mic=false&loopback=true , MediaElement.Source does not work for me)

Is there an efficient way for my problem. I am using Unity for my holographic app.

Thank you very much in advance

So i bought a HP mixed reality headset 3 days ago, and i can't get it working. I write this out of shear desperation.

The problem appears to be at the driver level. Windows just isn't able to install the damn Holographic Driver (Error 0x800f0206), as seen here:
https://gyazo.com/17ad73fc8c06951cfe1e44c3b64c6b31

Obviously, i've tried to update/reinstall manually from the device manager, but i get a "The install class is not present or is invalid" error.
Note: in the properties of the device i get a "The drivers for this device are not installed. (Code 28)" message as seen here:
https://gyazo.com/9f716786b025804148654baf376abf98

Before anyone says it, my PC is fully able to drive the MRH. Checked multiple times.

The setup software from HP has a "Next" button missing in the bottom right corner of the second screen of the setup process, meaning that the software literally doen't get to the point where it downloads/installs the driver and the Mixed Reality Portal (witch is missing on my computer). Don't know what it's causing it nor how to fix it tho. Tried Acer's software, the same issue happens.
My HP Setup second screen: https://gyazo.com/fed92e56ab5e8224bfae35e2b232d43b

I've made a fresh C: format and got Windows reinstalled, with no results.
SteamVR appears and executes just fine but doen't recognise the headset without drivers,

I've contacted Windows twice, and got exactly 0 help, so if anyone has even a hit of what the issue might be, please help?

Hey guys, so I have an issue with my Acer WMR headset, it used to work perfectly, but suddenly today half of the left eye just displays black... I've tried everything, rebooting, reinstalling WMR, even trying on a different computer, but no luck...

Here is a picture of the issue: https://imgur.com/a/SQyeS

If you know a fix or if you are experiencing this as well please let me know! It would be a hassle for me to exchange since I'm in Canada and I bought it off of someone on Kijiji so I don't have any proof of purchase or anything of that sort. Thanks!

-Bought a refurbished HP Windows Mixed Reality Headset. At first the Mixed Reality Portal wasn't recognizing my USB 3.0s. I looked that up and uninstalled the non-Microsoft eXtensible Host Controller, now the Portal recognizes the 3.0s.
-I have green checkmarks for everything in the Portal. When the Portal tells me to connect my headset I plug in the USB into a 3.0 slot, then the HDMI to the back of my GPU and nothing happens at all. I've checked the troubleshooting guide and googled the problem and haven't found a solution. I've tried all the other USB slots. I've successfully plugged a monitor into the HDMI slot. I've checked all of my drivers. I even uninstalled and reinstalled every USB driver and all motherboard drivers.
-The other end of the USB/HDMI cable that plugs into the headset got rather warm the first time I plugged it in, I don't know if that means anything.
-I plugged the headset into an older, non-compatible computer to see if anything would pop up. Nothing did.
-The controllers paired up fine through the bluetooth.
-I cannot install the drivers manually because nothing shows up in Device Manager when I plug in the headset.

Hello!

This is my first time using Hololens so I did everything from begining. I followed the online Holograms 101 tutorial.

Since I have a physical hololens, so I only followed the section "Installation checklist for HoloLens". I first installed a Unity 2017.4.2f2, then I installed a Visual Studio 2017 (15.6.7, community) with "UWP development" and "game development with Unity" selected.

Then I just followed the instructions in Chapter 1. Everything went well. In "Building Settings", I selected "Universal Windows Platform", "target device" is hololens, "Build type" is D3D, "SDK" is Latest installed since there is no option "Universal 10", "visual studio version" is Latest installed, "Build and Run on" is local machine, and I checked "Unity C# projects".

After opening the sln in visual studio, I set "release" "x86" "device"(my hololens is connected via usb) and then "start without debugging", and then I got the following 2 errors:

I have tried searching online for solution and I did see some people with the similar issue, but most of them are using an emulator instead of a real hololens. I have tried some solutions independent of emulator/hololens, but they didn't solve my problems.

Now I really don't know how to deal with it. I think the problem is from my visual studio because I also tried with my Unity 5.6 and it gave me the same errors. Another thing when installing the tools is that I just downloaded those listed under "Mixed Reality Toolkit", should I also build those solutions?

FYI, here are the settings of my visual studio:

And here is the player setting of my unity 2017.4.2:

Does anyone know how to solve the problem? I really need to make it work by next week and now I'm very upset

Thank you very much in advance for any help!!!

Have a nice weekend,

Jing

I have two computers and two HP Windows Mixed Reality headsets. I'm going to develop a VR application that cantains virtual scene corresponding to the real scene.Two pepole can walk in real scene with headset, and can see each other.
I have collected environmental data on the two computers. But I have a problem : how to keep two headsets's coordinate systems are consistent to ensure actual scene and virtual scene correspondence.

hello ,i need to create an application using hololens for clinical surgery, and i don't understand how to do the registration between the reel object and the hologram?
please can u explain me how they just did in these videos ?
thank you.

Hello, it's just for my report at university. i need to know the principal of the calibration that the hololens use. i can't find articles talking about. Thank you

I am trying to view my scene in the GameView but since I have an opaque device my game view is showing up blank. This only happens when I use the Mixed Reality Camera Manager.

So I had working version yesterday. But today my app acting weird. Microphone/speech recognition doesn't work in Release deploy, however when I do in Debug mode it works properly.
Any suggestion how to fix it?
I have enabled Microphone in Capabilities settings.

I am setting up Spectator View for a project that's under an NDA. This is my first time doing this, and I'm already running into some trouble regarding anchors.

On following the steps as outlined here:
https://www.andreasjakl.com/how-to-set-up-hololens-spectator-view-part-3-first-real-life-test/
one of the errors I get is as follows:

NullReferenceException: Object reference not set to an instance of an object SpectatorView.JoinSelectedSessionButton.Update () (at Assets/Addons/HolographicCameraRig/SV_UNET/Prefabs/Support/Scripts/UI/JoinSelectedSessionButton.cs:32)

Line 32 of JoinSelectedSessionButton.cs is
if (networkDiscovery.running && networkDiscovery.isClient)

The error exists because the static variable Instance of type NetworkDiscoveryWithAnchors is assigned null, as the starting code for that class did not find any objects that are of type NetworkDiscoveryWithAnchors. This debug output explains:

Expected exactly 1 SpectatorView.NetworkDiscoveryWithAnchors but found 0 UnityEngine.Debug:LogFormat(String, Object[]) SpectatorView.NetworkDiscoveryWithAnchors:get_Instance() (at Assets/Addons/HolographicCameraRig/SV_UNET/Scripts/NetworkDiscoveryWithAnchors.cs:33) SpectatorView.SpectatorViewManager:Update() (at Assets/Addons/HolographicCameraRig/Scripts/SpectatorViewManager.cs:298)

Right now in my scene I don't have any anchors. But before I add one into place, I want to make sure that upon adding one, this line
NetworkDiscoveryWithAnchors[] objects = FindObjectsOfType<NetworkDiscoveryWithAnchors>();
will return an array of length one.

I did try having the hologram I want to anchor to as a child of a game object with the NetworkDiscoveryWithAnchors script. That didn't work. I also tried making the hologram as a child of the UNetAnchorRoot game object that's part of the Sharing prefab.

What am I supposed to do? I feel like I don't need to do anything except just add an anchor to the scene (which I don't know how quite yet).
