Allow User to reset serial number
It appears like registration is a one time event. If that is true and you uninstall Aomei Backupper PRO from your computer and either move it to a different machine or you reinstall it on your present machine registration using the same serial number will fail requiring you to obtain assistance from your support group. Would it be possible to modify your code so that the user can un-register the serial number before un-installing Aomei Backupper? Or store the unique machine identifier so that the registration process will accept the serial number on the original registered machine more than once?
