Troubleshooting Failed Hamachi Client Setup

    When you have trouble setting up the client, here's what to do.


    You see the following error when you start the Hamachi client:

    Setup has failed


    There are two main causes of receiving this error message:
    • There is a corrupt profile from Hamachi v1.x.
    • Third party software is managing some aspect of the network stack. The two most notable are nVidia (via their NIC Drivers) and Norton.


    • Completely remove any and all files and folders regarding Hamachi, and clean the registry of Hamachi entries. Subsequently, reboot the computer and reinstall the Hamachi client.
    • Configure either third-party software accordingly.
