Cannot install TurboTax 2016 on my Mac from CD - getting (Error code -36)

I keep getting (Error code -36) trying to install TurboTax Deluxe 2016 on my Mac from CD. I tried cleaning the disk as suggested in the FAQ about this error. I bought the CD from Costco.
Should I return it? Exchange it?
Can I get a download that works?
Thanks!
