Hi @vlig96, thanks for taking the time to make an installer. Again, I am able to run the calibration screen without needing to press any buttons strangely.
However, I was not able to progress beyond the calibration screen itself.. the program simply closed after that.
Here was my experience @ https://files.fm/u/ax73df6q
In terms of solving the issue, have you looked at forcing the calibration windows to receive focus? It looks like this is the problem you may be facing.. once an ‘action’ such as start menu is loaded, the focus returns to the Quiz Window and you are able to proceed.
Perhaps this function should help @ https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setforegroundwindow
