Turbo Tax Home and Business 2012 W/ Multi Free State Instructions.

2012 Edition of Turbo Tax H&B. When installing you install from the Turbo Tax folder. The installer in main folder is for updates. You can download install updates from inside program so not sure what good if any that updater has.
For multi-State you need to know how to use regedit. Simply open Regedit. Find the Intuit Key under HK USer Software and delete entire key. When you reopen Turbo Tax it will ask you again if you want to reinstall another state and any previous installs still work. I tried it with my sisters returns since she lives in another state and worked without problem.
