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.

Hololens App: Is it Possible to Launch a Unity app from another Unity App

Hi, Is it possible to launch another Unity application from within a Unity application? If I Click a button in one application it would launch another application that is installed in Hololens. I would be very grateful if I could get example code on these specific requirement.
Thank You,



  • Hi Sreehari,

    On Hololens, it is not possible to launch another Unity application from within a Unity application at this time.

    Thanks for the suggestion and I will forward it on to the product team.


  • This is actually possible as long as you know the URI associated with the Unity app you can use launch URI to launch another Unity App.

  • Here's the regular UWP way to do it: https://docs.microsoft.com/en-us/uwp/api/windows.system.launcher

    That said, some apps like Skype don't seem to work -- so the launcher may behave differently on HoloLens.
