Activating the License

  1. Cut the received licence as the instructions in the email indicate.
  2. Create a text file in the name shield.txt and paste the required section in the text file.

  3. Save the license file (shield.txt) at the root of the software installation directory.

    WinCC OA requires a license file called 'shield' and if such a file already exists, replace it with the newly received licence.

    If the user has multiple versions of WinCC OA installed, ensure the licence file is copied to the correct version.

    Do not edit the license file and in case of an invalide license error message check the FAQ provided in the email or contact support teams via the provided links.

    A license is valid only for a period of 1 year and after this duration user must request another license. If the system settings were changed within the mentioned duration user will have to request for a new license.
