Change autohotkey tray icon from within script

How can I change the tray icon to my.ico from within an Autohotkey script for example when the script is paused. For this I have come up with my own Pause Script menu item in the tray menu. ``` #SingleInstance ignore Menu, Tray, Tip, AutoCase 0.11 Menu, Tray, Icon,,,1 Menu, Tray, Icon, D:\\Utilities\\AutoCase\\AutoCase-Icon-32x32.ico,1,1 Menu, Tray, Icon, D:\Utilities\AutoCase\AutoCase-Icon-(Paused)-32x32.ico,2,1 Menu, Tray, NoStandard Menu, Tray, Add, &Pause Script, PauseHandler Menu, Tray, Add, E&xit, ExitHandler Menu, Tray, Default, &Pause Script PauseHandler: Menu, Tray, ToggleCheck, &Pause Script MsgBox %A_IsPaused% if A_IsPaused=1 { Pause Off Menu, Tray, Icon,,1,1 } else ; <>1 { Menu, Tray, Icon,,2,1 Pause On } return ExitHandler: ExitApp return ``` When compiling the script, I face with an error warning that the icon file cannot be loaded. Please advise in this regard.
