Misconfigured path causes PermissionError within subprocess.Popen call

python runned from cmd with admin privileges. running any action, e.g. ahk.mouse_move(x=100, y=100, speed=30, blocking=False) will throw PermissionError:

It’s looks like need to run subprocess from admin privileges as well. For this need to add to subprosess.Popen these args before running AutoHotkey.exe executable:

'runas', '/noprofile', '/user:Administrator',

Ok, I delete AHK_PATH variable and now everything is works without extra definition to path.
