It's now automagically copied into the same Windows "folder" as your Aces High executable. If your installation follows the usual norms, it's at:
"C:\Hitech Creations\Aces High\ahedmiss.exe"
You will need to "drill down" into your filesystem to run it. Double-click on "My Computer", then "C:" then "Hitech Creations", then "Aces High", then "ahedmiss".
Windoze should then start it for you.
