Hi Fred,
installed both and working fine in the same windows 11 ARM64 machine.
little glitch, when right click in the icon and selected "Sleep", BT shows the task as "slept" but the task still running in the background of the computer.
but when BT starts, it properly starts BOINC and when click on "Start/stop local client" the action is properly done.
but the sleep in the right click of taskbar icon seem's not to perform the task, but as told before BT shows it as slept.
