The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
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.
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, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
Mixed Reality Technical Preview (MRTP)
I was given an Acer Mixed Reality Headset, but it didn't come with any documents. I've managed to download and install everything I need to run the headset and it's really great but I have no way of gaining access to the link to download the MRTP through Unity.
This is the link to the forum but it doesn't work unless you're granted access. Whom do I need to speak with to gain access?
