Just to confirm: reverting to the indicated earlier version did solve the issue.

Thank you for the quick reply. This would explain why my other project is working correctly.
And yes, that indeed sounds like my license.
For now I'll revert to an older version of QuickOPC. Can I upgrade the license to include support for new versions, or do I need a new license to prevent this from happening on future projects?

Hello.
Based on the email address associated with the account, I assume you are using the license key purchased on May 1, 2019. There was no upgrade assurance purchased with it, which means that the license covers only the QuickOPC versions that was current at the time of the purchase and/or released up to 60 days following that (and older versions). Using the table here: kb.opclabs.com/Versions , one can say that that key covers QuickOPC versions up to 2018.3 (5.54), but the error message indicates you are trying to use that key with QuickOPC 2020.3.
It is still somewhat unclear why the error messages says "Context: 0 dropped license(s)." - here I would expect it to list the actual license key you have embedded, so there may be an issue with the embedded registration as well, but if the license key is invalid for that version, try to resolve it would not bring success anyway.
If you are using a different license key, let me know.
Best regards

The error text we received was:
Run time is over the limit in license "Multipurpose", serial number 1111111120. The license you are running (most likely trial version) does not provide valid data after certain time period expires. Note that after the component's process is simply restarted, valid data will be provided again. Obtain and install proper license to permanently resolve this error.
Product information follows. Component name: "QuickOPC", license IDs: "Multipurpose", version number: 559, release date: 12/3/2020, trial validity: 397 days, option expression: "EasyUAClient".
Context: 0 dropped license(s).
+ The client method called was 'DataChangeNotification'.

Can you please let the code run (and do OPC operations) for 30 minutes, and then capture the full error text of the exception you get ? (the exception will indicate that the "trial license" is being used; we need the additional info that should be in there).
Many thanks

Hi, Based on code from:
opclabs.doc-that.com/files/onlinedocs/QuickOpc/2018.3/User%2...esource%20License%20Store.html
we have made this C# code:
string _resourcename = _assembly.GetManifestResourceNames().FirstOrDefault(str => str.EndsWith(LICENSEKEYNAME));
if (!String.IsNullOrEmpty(_resourcename))
{
Framework.LogLow(LOG_SOURCE, $"Found EasyOPC license in {_assembly.FullName}", _resourcename);
LicensingManagement.Instance.RegisterManagedResource("QuickOPC", "Multipurpose", _assembly, _resourcename);
_client = new EasyUAClient();
_client.DataChangeNotification += Handle_VariableUpdated;
_client.QueueCallbacks = false;
// Obtain the serial number from the license info.
long serialNumber = (uint)_client.LicenseInfo["Multipurpose.SerialNumber"];
However, despite our logs indicating it finds a valid embedded license resource, the serialNumber we receive is "1111111120", which indicates an invalid or trial license.
What could cause this? If necessary I can email you the .bin file we have embedded in the assembly.
