- Download a version lower than your current one via the download page of AutoHotkey
- Extract the folder to C:\Program Files\AutoHotkey
- Open the dash
- Select "Launch settings"
- In "Preferred interpreter by major version", select the "Latest 2.x" drop-down menu
- Select the version you downloaded
- Close the "AutoHotkey Launch Config" window
- Select "Launch settings" again
P.S. Is it Launch Settings or Launch Config? Also, I can't seem to get the numbered nor alphabetical lists to work on the forum.
