WinCC 7.5 / "A basic application could not be started" message

The error "A Basic Application Could Not Be Started" in WinCC 7.5 typically indicates a corrupt installation, missing updates, or software incompatibilities rather than just a simple licensing issue. This "basic application" often refers to the SQL Server or the WinCC Project Manager failing to initialize. Immediate Troubleshooting Steps

Check Software Compatibility: Ensure your version of Windows (e.g., Windows 10 22H2) is compatible with your WinCC version. You may need to install a specific service pack or update, such as Update 15 for WinCC 7.5 SP2, to resolve stability issues on newer Windows builds.

Run Reset Tool: Use the reset_wincc.vbs tool located in the WinCC installation directory and then restart your computer to clear hung processes.

Verify User Permissions: Always start WinCC with the same user account used during the initial installation to avoid permission-based startup failures.

Check Windows Event Viewer: Look for Event ID 10010 (DCOM registration timeout) or other errors under Windows Logs > Application to identify if the SQL server failed to respond. Advanced Solutions

Reinstall SQL Instance: If the SQL server instance was not installed correctly, the project manager cannot start. Some users recommend uninstalling both WinCC and the SQL instance entirely, then reinstalling them. Ensure your computer name does not contain special characters (like underscores), as this can break SQL installations.

License Verification: Although the error message often mentions licensing, verify your license status in the Automation License Manager. If the license is missing or invalid, WinCC may fail to open existing or new projects.

Network Check: If your PC is not connected to a network, the project may take a very long time to open or fail if it cannot find the terminal bus. Ensure your network cards are correctly ordered and functional.
