Hello
Each activition string is valid for each machine. If you reformat your machine, you can re-use that activiation string. But if the hardware configuration on you machine changes ( different Hard driver, network card etc..) then you will need to re-activate the CVI again. You wont have to buy an additional licenses to do this. Check out this
link for more information.
