Hi, I did try that. Unfortunately it then acts like I've removed OPC entirely. The imports are green underlined.

I apologize for not knowing what I'm doing with this. I usually only do .net apps connected to Databases, not PLCs.

Thanks,

John

Hello.

Please send the full precise text of the error you get in the EasyUADataChangeNotificationEventArgs .

Do not worry about the licenses.licx file, although it appears in the project, it is not actually used in license validity determination.
There should be a License Manager utility installed with QuickOPC, and when you run it, your license should appear in the list. Can you find the utility and post the screenshot?

Best regards

Hi- We think we have a license 1954229880, but we aren't sure. What kind of license is this? The developer who was using it died suddenly and left us very little documentation. We're trying to run the program he wrote locally to debug it, but we get an error on EasyUADataChangeNotificationEventArgs that our license is expired. I never used EasyOPC on my local PC. Our licences.licx file doesn't appear to include our license number, so do we need to change something there? "OpcLabs.EasyOpc.UA.Connectivity.UAConnectivity, OpcLabs.EasyOpcUA, Version=5.41.1036.1, Culture=neutral, PublicKeyToken=6faddca41dacb409"
