> Hi guys, I have freshly installed the latest version of Automation Studio AS 4.12 on a Win11 machine. System info give me: Microsoft Windows 11 Home Version 10.0.26100 Build 26100 PC: Acer A517-58GM When I start AS4.12 the splash screen appears for a second and then nothing happen afterwards. Also no error message appear whatsoever. I installed version AS 4.12.6.106 during the regular installing process. Any idea what went wrong?
