This usually happens when the downloaded file is incomplete, blocked by your antivirus, or because extracting the installer with 7-Zip removes important file properties. Before trying the solutions below, make sure:

You downloaded the installer from the official AutoHotkey website.You have administrator privileges.Your internet connection is stable.

If the issue persists, try these fixes:

1. Disable Antivirus Temporarily

Sometimes antivirus programs mistakenly block installers. Turning it off for a few minutes can let the setup run smoothly. Remember to turn it back on after installation.

2. Install Using Command Prompt

This method skips 7-Zip completely and downloads the installer directly.

3. Download and Run Installer Directly

The easiest fix is to run the installer without extracting it.
