Actually you can use just 1 version. All the Desktop programs have the same forms. So you can use Deluxe for all. I would try to get a refund for one of them.
But here's how to activate a different version. There is a way to have 2 licenses. You don't need to install the second version just enter the License Code. Under Help - Switch Product - Activate new product. Don't know what that will do or what benefit you will get. Don't think it will allow you to efile more than 5.
