So i am running win 10 preview build, in preparation for it's release soon.
I had a problem with ED launcher not staying open long enough to launch the game, it would just keep disappearing and take a few attempts to run the game.
I have found the cause to be the AMD Gaming evolve app, which runs on windows 10 start. (for my recording really)
Now when i shut this down the launcher stays open and the game loads normally.
Just a warning to those that might have this issue, and also, if you know of a work around, please post.
Note: i am running the latest amd drivers, Omega 14.12, not the windows 10 default version.
I'll keep this forum topic open so that others can discuss issues with Windows 10 similar to yours. However, for taking care of your specific issue, I will address those in your ticket (Ticket # 12925).
