Sorry you can only have 1 program installed for each year on the same computer. Why do you need more? Did you buy 3 copies? You only need 1. All the Desktop programs can do unlimited returns and efile 5. And All the Desktop programs have the same forms. You just get more help and guidance in the higher versions. So you could use Deluxe for all. You can install Turbo Tax on 5 computers you own.
And each return is saved in a separate data file so you won't mix them up or overwrite them.
