Installing PrintMaster Platinum 16

I am trying to install PrintMaster Platinum 16 back onto my wife's computer. We had to upgrade her operating system so this requires reinstallation of the other programs.

She wants it reinstalled so she does not have to change discs everytime she tries to make a card, as she makes lots of cards to give away to sick, encouragement, etc.

Could you give me the steps I need to take to fully reinstall this program onto her computer so she doesn't have to change discs? Thank you for your help. Jim.
