Just unzip the Haps.zip file and extract all the .hap files to the Characters folder in the Ultra Hal Assistant 6 directory.
This is where my Charaters folder is located and it is probably the same for you.... I hope.
C:\Program Files\Zabaware\Ultra Hal Assistant 6\Characters\
The charaters folder is where Hal's charaters, backgrounds, and anything related to Haptek is located. This is where you need to copy the .hap files to.
