Click the link above. You will get a window asking if you want to open the file or save the file.
If you just want to print the powerpoint slides:
Select open (with Powerpoint), hit ok.
Once in Powerpoint, go to file, Print, halfway down the window it will say "Print What", change the selection from "slides" to "handouts" and to the right, change it to 3 slides per page. This will give you 3 slides on the left side of the page and lines for notes on the right side of each page.
If you want to save the powerpoint file:
Select Save, change the directory to where you want the file saved, and hit ok.
