After you get the program reinstalled the first thing to do before you open your tax return is to update the program and install any state programs you had. Then open your file. So you first might need to start a fake return to be able to download the state program (go to FILE - NEW).
Error 190 for state

You reinstall the federal program -> run update -> download the state program -> run update. Then make sure the .tax file is copied to new computer. Do not Open that file from the transfer medium.
What I would do is just copy the whole Turbo Tax folder that is under your Documents. That should be where the .tax files and pdf files are stored. Copy that folder to a flash drive or best yet is to burn it to a CD or DVD and then you will have a backup of them. Then on the new computer copy the folder (or files) from the flash drive to your Documents folder.
You only need the prior year .tax file to transfer into the current year. And actually you should open each year (if you still have the programs installed) and save each year as a pdf file if you haven't done that. Then you don't need the program installed to view your returns.
