If my laptop will broken or I will need to re-install my Win11, can I use my own serial number on new laptop or new OS?
Hello Jahor, yes , as long as you login to your Native Access with the same account that you have your Traktor registration with everything should work smoothly and you will have access to your product in any computer.
So as mykejb also says, downloading the Native Access to your new computer and logging in with your Native Instruments account will be enough to make use of your product.
I hope this helps☺️
Install Native Access on the new PC, log into your account and install Traktor. That's all you have to do :)
