What is AU3_Spy.exe? Where can I find it?

Whenever I try to launch the Windows Spy utility in AutoHotkey, it fails with an error “Could not launch file: U:\Software\AutoHotkey_1.1.26.00\AU3_Spy.exe

Initially I thought that I may have had a corrupted download. However, after redownloading AHK from the official website, I could not find any file named AU3_Spy.exe in ahk.zip.

After some research, I’ve discovered that the portable version of AHK is missing AU3_Spy.exe, which seems to be required for Window Spy to run.

  • What is AU3_Spy.exe?
  • Why wasn’t it included with AutoHotkey?
  • Where can I find the missing file?
