You can install it on 5 computer you own. You are not suppose to share it . I just installed my Costco CD today. I used the download method instead of the using the CD. I bought the CD in the store,. If you buy it online it is the Download. Be sure to pick the right download....Windows or Mac. The CD has both the Windows and Mac programs on it.
And if you buy the Desktop CD/Download program you can buy a lower version. All the Desktop programs have all the same forms so you can use a lower version like Deluxe for everything.
