Hello, I am a student trying to install Creo 12 Academic Version. I am encountering a persistent issue during the licensing step: The Issue: After entering my Product Code (BK...), the installer displays a green "Success" status. However, I cannot proceed, and the generated license file in C:\ProgramData\PTC\Licensing is empty (0 KB). Technical Details: Version: Creo 12.0 Host ID: [Available upon request for PTC Staff] Product Code: BK120908EDUNIVERSITYED Troubleshooting already done: Ran the installer as Administrator. Disabled Windows Firewall and Antivirus. Verified that the Host ID matches my active network card (other adapters were disabled). Cleared the Licensing folder and attempted a re-install. Verified that the "Controlled Folder Access" in Windows is disabled. Despite the server validation (Success), no data is written into the .dat file. Could you please provide a valid license file or reset the activation for my Host ID? Thank you for your help

    To provide more context for the support staff, here is my current ipconfig /all output.

    Configuration IP de Windows

       NetBIOS sur Tcpip. . . . . . . . . . . : Activ‚

    As you can see, I have already:

    1. Disabled IPv6.

    2. Disabled all other secondary or virtual network adapters.

    3. Confirmed that the Host ID 2C-F0-5D-D3-94-E8 is the only one active.

    Despite this clean setup, the license file generated by the installer remains at 0 KB. I hope this helps in generating a manual license file for me.

    Thank you!
