While try to start RF-TENDON I get the message "the application is locked by external COM connection". What is the problem?


RF-TENDON is an external add-on module. While RF-TENDON is running RFEM is locked via COM connection. RF-TENDON is not integrated in RFEM and it runs as a separate application. RF-TENDON should appear in the taskbar after it was started (picture 1)
