Help in closing all windows through Applescript.

[ubaldot]

I wrote the following Apple script:

This script tell application "IINA"
	if it is running then
		delay 0.5
		close every window of it
	end if
end tell

but it returns:

error "IINA got an error: every window doesn’t understand the “close” message." number -1708 from every window

Does anyone know how to fix it?
