Can I load my 2017 on a 2nd computer for my son to use? I have used one of the five filings. Can the Wisconsin product then be downloaded to this computer as well?

From FAQs it seems like I am allowed to load the 2017 Deluxe disk to a second computer but then can the Wisconsin state product be downloaded to this product? I used Wisconsin for my state return. For my use, it was loaded onto a MAC, but I am not certain if his laptop is a MAC or not but suspect it is not.
