Hello, and thank you for the answers/

In #1, I do not quite understand why you mentioned TCPClient.Disconnect. Is TcpClient something you use inside your project? Because, it is not a QuickOPC class, so I am not sure why specifically this is mentioned.

In #5, what I meant is any method on EasyUAClient that starts with "Subscribe" - such as SubscribeDataChange.

Or (additional question), are you using WPF with our Live Binding feature? ("codeless" - just configuring the relations between on-screen controls and the OPC values)?

Best regards

1. It seems weird that only an installation of the license would have caused this. Hasn't anything else changed? For example, isn't the error on a different computer, or with a new version of QuickOPC?
=> Only in the station PC on the Site. Only during closing of the application after TCPClient.Disconnect().

2. If you now uninstall the license (using License Manager), does the error go away?
=>If you now uninstall the license, the error doen't go away.

3. Are you using OPC Classic or OPC UA (I think it is OPC Classic)?
=> OPC UA

4. Is your application running in 64-bit, or in 32-bit process?
=> 64-Bit

5. Are you using subscriptions?
=> What do you mean with subscriptions?

6. What type of project are we talking about? (e.g Windows Forms, WPF, Web service, Web app, Windows Service, console app, etc.)?
=> WPF-Project.

7. Do you get the error always, or just sometimes?
=> Always.

8. Which QuickOPC version are you running?
=>QuickOPC 2018.3

Many thanks in advance
Best Regards.
