Long time ago I was using AutoHotkey
Below is Autohotkey script
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
#e::
RUN "F:\Program Files\MultiCommander (x64)\MultiCommander.exe", "F:\Program Files\MultiCommander (x64)", MAX
And attachment is registry edit
