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.
Mixed Reality Portal Opens Then Immediately Closes
I've just attempted to get setup for the first time. I'm intending to use the Mixed Reality Portal in Developer/Simulation mode until I have an immersive headset.
After installing prereqs per the Install the Tools developer article, I proceeded to the Using the Windows Mixed Reality simulator article. After choosing the Setup for simulation choice, I waited while it stated it was installing additional necessary packages.
At some point, the window just went away. I eventually tried to relaunch the portal. After a brief window display, it again went away. I then rebooted and tried again. Still no luck. Each time I attempt to launch, it just shuts down. No message is provided.
I checked the Event Viewer and I can see an Application Error is reported:

Is this a unique issue for me, or does it fit some known problem with some specific steps to resolve?
