Partition Commander does not require a serial number. We only ask that you register Partition Commander with us. Upon registering you will immediately receive a reply email with your registration code.
You may register the first time you use Partition Commander. The registration page comes up before launching Partition Commander. Use the link on the page to get to the registration page on our website. Alternatively you can continue to click 'Later' to bypass the registration screen and continue to use Partition Commander. The registration page will continue to come up before launching Partition Commander until you enter the registration code.
Partition Commander does have a serial number located in the installed program under HELP > ABOUT.
