The Automation License Manager (ALM) is the central tool for managing licenses. Conflicts can arise here from two common scenarios:
:
The error arises from a fundamental misunderstanding of the licensing structure. A SIMATIC WinCC Runtime Advanced license covers the number of PowerTags (process tags). However, the . If your project has configured any historical data logs (data logs or alarm logs) under the "Historical Data" editor, this triggers the requirement for a WinCC Logging for Runtime Advanced license. A WinCC Runtime Advanced license on its own, regardless of its PowerTag count, is insufficient for logging.

The message often appears intermittently (for example, every 5 minutes), and while it can be temporarily dismissed, it will keep coming back. In some cases, the alarm logging may still function during a grace period before eventually switching to a "Demo Mode," which can be catastrophic for production environments.
: If the license is already installed but shows as "defective" in ALM, it may be due to an improper system shutdown. You can attempt to repair it using the Restore function in ALM or contact Siemens Technical Support .
If you have confirmed the license is present in ALM but the error persists, try right-clicking the license in ALM and selecting to verify its integrity. However, the
: For PC-based stations, Siemens uses a modular licensing model. A standard Runtime license only covers basic visualization; logging and recipes are always separate add-ons.
The "License Key Not Available" error for WinCC Logging in Runtime Advanced Link can be a frustrating issue for users of Siemens' WinCC (Windows Control Center) software.

Sometimes the license exists, but Windows picks the wrong one.
If you are seeing the "License key not available! WinCC Logging for Runtime Advanced" error, it is typically because WinCC Runtime Advanced handles logging differently than Comfort or Basic panels. While panels often include logging capabilities in their hardware price, PC-based Runtime Advanced requires a dedicated separate license for any data or alarm logging. 1.
