I have been having this problem for a while now. Newly built custom PC, Windows 7, 16gb ram, 2tb hdd. I have tried everything I have found suggested to fix this issue from disabling AV/Firewall to restarting in selective start mode with everything non microsoft disabled and i keep having the same issue. I open the launcher and the icon shows up down by the clock. When i clock on it it shows on the taskbar but the launcher is not visible. Every other game/program I have works normally, with the exception of GeForce Experience which has a similar issue.
Can someone please suggest something else? The game works flawlessly on my Macs but I would rather play it on my Win7 machine I build specifically for gaming.
