Computer limit

Hi. I want to make my software key able to be used only ONE time. So, if they install it, they cannot install it on another computer. Even if they uninstall it, that key will still be used and shouldn't work. So a one time use key. What settings should I put? Thanks, lmk asap! 😀

Create a product key with 1 allowed activation and 0 allowed deactivations. That way the customer always has to use it on that computer and can never move it.

Thanks!
