TIA Portal v11 Installation Issue with WinCC Flexible 2008

Hello,

We understand you're facing issues installing TIA Portal v11 on a system with WinCC Flexible 2008 already installed. The successful installation on a system *without* WinCC Flexible 2008 suggests a conflict.

Possible Solutions:

  • Compatibility: Verify that TIA Portal v11 is fully compatible with WinCC Flexible 2008. Check the Siemens Compatibility Tool.
  • Installation Order: It's generally recommended to install TIA Portal *before* WinCC Flexible. If possible, consider uninstalling WinCC Flexible 2008, installing TIA Portal, and then reinstalling WinCC Flexible (though this isn't always seamless).
  • Administrator Privileges: Ensure you're running the TIA Portal installer as an administrator.
  • Firewall/Antivirus: Temporarily disable any firewall or antivirus software during the installation process.
  • .NET Framework: Confirm you have the correct .NET Framework version installed (as specified in the TIA Portal documentation).
  • Check Installation Logs: Examine the TIA Portal installation logs for specific error messages that can provide further insight. These logs are typically located in C:\ProgramData\Siemens\TIA Portal 11\Installation.

For detailed troubleshooting, please refer to the FAQ on Siemens Support. If the problem persists, gather the error messages and system specifications, and create a support request via SiePortal.

Thanks and regards,
Siemens Self Support
