When is the Runtime license not recognized with a Windows Embedded System?

  • Entry
  • Associated product(s)

Description
The license is displayed correctly in the Automation License Manager, but not taken by the corresponding Runtime software. When you start WinAC RTX and/or WinCC flexible Runtime or WinCC Runtime Advanced, you get this message: "No valid license key can be found". This behavior can occur when a CF card from a third-party manufacturer is being used in the SIMATIC IPCs. Some of these CF cards are recognized as removable media. However, a license can only be used if it is on a hard disk medium. A license can only be transported on a removable medium (also USB stick or floppy disk) but not used.

Instructions
This behavior does not occur if you use a SIMATIC CF card that is designed for the SIMATIC IPC. SIMATIC CF cards are always recognized as hard disk media in the SIMATIC IPCs.
An overview of the released storage media is given in Entry ID: 21847868.
