EDIT: I finally got it!
Here are my tips:
I couldn't download ImageSearch15.au3 (the one that's not part of the zip)
In ImageSearch2015.au3, there is an Exit statement that needs to be moved inside the If block!
If AutoIt is crashing, look at your ImageSearch file and delete any reference to the variable $HBMP
In Windows 10, instead of being able to select a screen resolution it now has a zoom amount...? Set that to 100% or else it may not work and may give you incorrect $x and $y coordinates
