You are correct, that link also 404's for me.
If you click on the small icon showing a letter 'H', however, that will show you the AutoHotKey code.
With the free AutoHotKey software you can either run that code yourself or compile it.
The AutoHotkey material is available from this link: AutoHotKey Web site
On the other hand, as a stop-gap measure, if you need someone to compile the code and upload the program, leave another message here.
