unable to run scripts with ahk_h

[haomingchen1998]

I want to replace my current AHK 1.1.36.02 version with AHK_H for true multi threading. But I can't run my scripts even if I create an empty script. I followed HotKeyIt's steps from below link:
viewtopic.php?f=67&t=75919&p=328810&hilit=install#p328810

1. I copied Compiler folder from ahk_H, paste in the old ahk folder, and replace files with same name.
2. I opened x64w_MT folder from ahk_h and copied AutoHotkey.exe, then replaced the AutoHotkey.exe file from the old ahk folder.

I didn't do anything to the Autohotkey.exe file from the programs > Autohotkey path as shown in the picture, I believe this is just a shortcut path, so I leave it untouched. Let me know if this is the problem. Thank you!
