How to Fix 7‑Zip Error When Installing AutoHotkey?

Whenever you try to install AutoHotkey by extracting the installer with 7-Zip, you may encounter an error dialog instead of starting the setup. In some cases, Windows may simply refuse to run the file without explaining why, leaving you unsure whether the file is damaged or blocked.

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.

1. Close the AutoHotkey installation window.
2. Press “Windows key + X” and click Settings.
3. Go to Update & Security > Windows Security > Virus & threat protection.
4. Click Manage settings and toggle Real-time protection to Off.
5. Run the installer. When finished, turn your antivirus back On.

2. Install Using Command Prompt

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

1. Search for Command Prompt, right-click, and choose Run as administrator.
2. Type the following and press Enter:

   curl -#LO https://www.autohotkey.com/download/ahk-install.exe && ahk-install.exe

   

3. Download and Run Installer Directly

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

1. Open your browser.
2. Visit the official AutoHotkey website and download the ahk-install.exe file.
3. Double-click the downloaded file (don’t open it with 7-Zip) and install it directly.
