I use AutoHotkey  in almost all my application but I notice some Qt applications (Like ADS) had some difficulty interpreting the AHK keys correctly. The problem turns out to be affiliated with UAC and Admin rights rather than the Qt library. To solve the issue simply add following lines to the top of your AHK scripts that you want to be applied on the specific app.

#SingleInstance Force
SetWorkingDir %A_ScriptDir%
if not A_IsAdmin
   Run *RunAs "%A_ScriptFullPath%" ; Run Script as admin

This problem arises when you open a software instance with the admin rights while the AHK script doesn’t spawn with the same permission level. The above script simply run AHK with admin rights too so whether application is with or without admin right AHK script will always be able to set the key bindings.
