AutoHotkey Not Working? Common Errors & Fixes

v2 is not backward compatible, so v1 scripts fail or do nothing. Install v1 for old scripts, or port the syntax and add #Requires so the right version runs.

This error almost always means v1-style code is running under v2. Fix the syntax or run the script with the matching version.

Windows UAC blocks normal scripts from elevated windows. Run the script with UI Access (best) or as administrator.

AHK and compiled scripts are often false positives. Verify on VirusTotal, report to the vendor and add an exclusion for your own file.

Many anti-cheat systems block or flag AHK. Close it before launching the game, and avoid scripts that give gameplay advantage.

Games often ignore normal simulated input. Try longer key delays, down/up events or ControlSend; some anti-cheat games block it entirely.

Send can re-press a modifier you already released. Use SendEvent, add small delays and tap the modifiers to clear it.

Letter hotkeys depend on the active layout. Bind by scan code (for example sc010) so the hotkey works on any layout.

Hotkeys can lag when the PC is busy. Raise the script's process priority and trim slow loops.

Put a shortcut to the script in your Startup folder (shell:startup). Use Task Scheduler if it must run elevated.
