Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Emulator running in VM - but error now

Is there a document on how to set up the VM for the Hololens emulator? I didn't even realize that I needed to... But finally figured that out, thru guessing and reading other trouble questions. So now I have set up a VM thru Hyper-V manager, and can run the Emulator... but am getting this message: Emulator is unable to verify that the virtual machine is running.

    1. Did you make the Hyper-V connections yourself, instead of Visual Studio Update 2 and the HoloLens Emulator?.
    2. Did you install in sequence given in install_the_tools
    3. Did you get a message about requesting to use Administrator mode for the first start.
    4. In Network and Sharing centre, can you see a connection labelled vEthernet (Internal Ethernet Port Emulator NAT switch), and in properties, connection: "Hyper-V Virtual Ethernet Adapter #2". If the answer is NO the you are going to need to uninstall the HoloLens Emulator, delete the Hyper-V Network controllers in Device Manager. Re-install the HoloLens Emulator SDK again.
    5. Use the simple VC++Universal Windows Holographic template, in VS2015, set to Debug,X86, Remote Device HoloLens Emulator and Deploy. This will hopefully make the new Hyper-V connections, and then trying to run the template under normal debug.

    There is a known bug in Windows 10 which on build 14295 leaves a RED x on the network icon , due to the TWO Hyper-V adapters being installed.

    Look for reconfiguring Hyper-V switching in this post
