    Moving or transferring a Nitro Pro license

    When moving Nitro Pro from one machine to another, we highly recommend deactivating the license prior to the move to ensure proper reactivation on another device.

    First, you’ll need your serial number.

    Locate your serial number

    Then, deactivate Nitro Pro by selecting the Help ribbon > About Nitro Pro > Activation > Deactivate. You are then free to uninstall Nitro Pro.
