@solomank Since you now have to log into an Intuit Account when you first install it, all your downloads and licenses are listed there (even if you bought it from somewhere else) so if you need to install it again or install on another computer, even on the other operating system (Windows, Mac) you can download it again.
Access your downloads here

You can burn the installation file to a CD or save to a usb flash drive. My Windows Download program is listed under Downloads and is named Windows_PC_TurboTax_Downloads.exe
