What I did was save the Studio One program file on my old computer to a flash drive, and then load it onto my new computer. I clicked on the installer, and it loaded with no problems whatsoever. You will be prompted to enter your license key, just like when you loaded it onto your old computer. If memory serves, you are authorized to run Studio One on more than one computer (don't quote me on this, but I'm pretty sure you can run Studio One on at least 3 computers). So you don't need to uninstall Studio One from your old computer.
