TIA Portal V14 Licensing Issue - Siemens Self Support

TIA Portal V14 Licensing Error on Windows 10 Home

Hello,

The error you are encountering with TIA Portal V14 and the Automation License Manager is commonly seen on Windows 10 Home editions. This is because TIA Portal V14 requires Windows 10 Pro for full functionality and licensing.

Resolution:

  • Upgrade to Windows 10 Pro: The recommended solution is to upgrade your Windows 10 Home edition to Windows 10 Pro. This will provide the necessary features for proper licensing.
  • Virtual Machine: As a workaround, consider installing TIA Portal V14 within a Windows 10 Pro virtual machine (e.g., using VMware or VirtualBox).

For further details and troubleshooting steps, please refer to the following SiePortal FAQ:

TIA Portal: License Error - "The licensing of STEP 7 Basic could not be completely finished"

If the issue persists after upgrading to Windows 10 Pro or using a virtual machine, please open a support request through the Siemens Support Portal, providing screenshots of the error messages.

Sincerely,
Siemens Self Support
