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.

Can we use a PC without Unity to host the Sharing Service for a shared experience ?


I work in a company with strict policies concerning security.
I am allowed to have two computers : one with unity but completely out of any network (I can't even plug it to a local router), and another one without unity but on which I can plug it to a local router emitting Wifi (both my HoloLens are connected to it) but I am only allowed to launch executable files on this computer, so I can't install Unity (or anything else) on it.

Is it possible to create a scene on the first computer, build it on my two HoloLens, and launch the executable files "SharingService.exe" and "SessionManager.UI.exe" on the second computer connected to the router ? Maybe I can enter the IP adresses given from this PC in my scene but since I haven't been able to try anything yet I don't know if it would work.

Thank you for your support.

  • Wonderful, thank you.

  • I am not able to run SharingService.exe without Unity, getting 'Service failed to run w/err 0x0000427' error after running. Anyone has any idea on this ?

  • you can start the SharingService in cmd, if you add "-local" as a parameter. For Example:
    [PATH to your Unity Project]\Assets\HoloToolkit-Sharing-240\Sharing\SharingService>SharingService.exe -local
