The error "License key not available!

If using Network License Manager:
- Check Archive Sizes: The "Logging" license sometimes has constraints based on the number of Power Tags or Archive variables. If you configure 500 archive tags but your license only supports 200, the system may fail to initialize the logging service, resulting in a license error.
- Check Storage Paths: If you are running Runtime Advanced on a PC and directing logs to a specific SQL instance, ensure the SQL server is accessible. While usually a connection error, if the logging service crashes on startup due to a bad path, it can sometimes incorrectly flag a license issue to the user interface.
Damaged License Keys: If you have the license but still see the error, it may be marked as "defective" in the Automation License Manager (ALM) due to an improper IPC shutdown. You can attempt to restore it or contact Siemens Technical Support.

Preventive Measures: How to Avoid This Error in Future
- Document Your Licenses: Keep a spreadsheet of all license numbers, version compatibility, and type (floating/station).
- Use the "License Management" Checklist: Before deploying a runtime PC, run ALM to generate a license report (File > Save as... > License Information File). Verify the logging option is present.
- Separate Engineering from Runtime: Do not install both WinCC Engineering (development) and Runtime licenses on the same PC unless necessary. Conflicts can occur.
- Regular Backup of License Files: Use ALM's "Backup License" feature to save
*.LicenseFile to a secure network drive.
- Avoid USB Hubs for Dongles: If using a USB dongle (less common for newer software, but still in legacy systems), plug it directly into the industrial PC's rear USB ports. Avoid front ports or extender cables.
