Connect your laptop to the Internet and run the pscan software. It will automatically update itself.
You don't need the interface box or a connection to a car to do this.
If you have not installed the pscan software at all please follow these instructions
https://pscan.uk/install/
The only exception is if you are running the old pscan.eu software from a few years ago, that will not automatically upgrade. If you have this then please reinstall from the above link.
