No, you do not have to keep previous years of TurboTax installed on your computer. As long as you have your CD it can be reinstalled. Or, if you purchased it from TurboTax and downloaded it to your computer, it can be downloaded again.
It is important that you keep your .tax20xx data files though. These will be needed in order to access your prior year tax returns.
