I click start button, and start typing (searching) EDMC, and it shows the app, and it shows options for open, run as admin, pin to start, pin to task, unistall... and so on. I click Pin to Start, and then click that. I stopped doing that because it disappears on me, so I search for it and click run. I recently read that Odyssey Material Helper performs the same base function, so I've just been using EDMC to update my Inara.cz stuff here and there, because it says in the App EDDN prefers only one app used to upload data.Also a possibility , but how @Crumly starts we still don't know. And he has/had the problems.
Thanks for the idea to paste the link.
It does show up in the Start Menu when I click "All Apps", just can't keep it pinned. Maybe when it updates something happens
