# AutoIt (slim)

> AutoIt v3 is a freeware BASIC-like scripting language for automating the Windows GUI with simulated keystrokes, mouse movement and window and control manipulation. Agents run scripts through AutoIt3.exe, and AutoItX exposes the same functions through a DLL and COM control.

## Before you call it

1. Pass `/ErrorStdOut` so a fatal error reaches stdout instead of a dialog
2. Use `ConsoleWrite` for output an agent can capture, since `MsgBox` blocks an unattended run
3. Check `@error` after each call. Functions report failure there, not by raising
4. Install the official package from autoitscript.com. NuGet copies of AutoItX are third-party repackages
