[Sorry, I made a mistake, I meant 2024.1, not 2024.2, but that does not affect the reasoning provided]
Assuming that you are using QuickOPC from .NET (and not via COM interfaces like from VB6), it doesn't matter whether QuickOPC 2024.1 was installed on the machine or not.
What matters is what version of QuickOPC you have used when you have built the application. I am 100% sure that you have built it with QuickOPC 2024.1, because the version number is embedded in the software, and it is what the exception message says.
Best regards

The device I'm running this on doesn't have QuickOPC 2024.2 installed.The problem may stem from how I upload the application to this device. Is there something in the QuickOPC app I need to change?
Thank you,

The software that has thrown this exception is not using QuickOPC 2021.2 as you stated. In fact, it is using QuickOPC 2024.2 (internal version 5.80), which is not covered by the license key, and that's why it is giving the licensing error.

My application subscribes to multiple data changes over 80 or so nodes and updates a GUI based on their data. We have a logging system for this application and I noticed that it was being filled with the exception below almost every second. It seems to be a licensing issue but this is the only node out of ~80 that is throwing it.
I'm using OPC Labs QuickOPC 2021.2

The status is showing active but it seems like its getting dropped? How can I fix this?
Thank you,
