Hi there,
These issues occurs rarely in Windows PRO upgrade . The simplest way would be to reset the PC and then try the update.
Open Recovery settings or select Start Windows logo Start button > Settings Gear-shaped Settings icon > Update & Security Circular arrows Sync icon > Recovery.
Under Reset this PC, select Get started.
The next option is to change the the Key in the activation and use this default key which will trigger the upgrade.
