Hello!

I have installed the wrong license on this system.
Since we already have a new license, I will register the new one on the system.

Thank you for your help.

You cannot use version 5.52 with your license. The license has been issued 10/17/2014 with upgrade assurance 1 year, till 10/17/2015. But version 5.52 has been released on Feb 13, 2018, see kb.opclabs.com/Versions .

You need to revert to an older version, or purchase a version upgrade.

Best regards

Hello,

1. How was the license installed onto the system? Using License Manager, or by some other method?
2. Please send me the serial number - email to support09 (at) opclabs.com .
3. Is it on the 32-bit or 64-bit system?

For checking the license in runtime:
// Shows how to obtain the serial number of the active license, and determine whether it is a stock demo or trial license.
 
using System;
using OpcLabs.EasyOpc.UA;
 
namespace UADocExamples.Licensing
{
    class LicenseInfo
    {
        public static void SerialNumber()
        {
            // Instantiate the client object.
            var client = new EasyUAClient();
 
            // Obtain the serial number from the license info.
            long serialNumber = (uint)client.LicenseInfo["Multipurpose.SerialNumber"];
 
            // Display the serial number.
            Console.WriteLine("SerialNumber: {0}", serialNumber);
 
            // Determine whether we are running as demo or trial.
            if ((1111110000 <= serialNumber) && (serialNumber <= 1111119999))
                Console.WriteLine("This is a stock demo or trial license.");
            else
                Console.WriteLine("This is not a stock demo or trial license.");
        }
    }
}

Best regards

On one of out testing systems we observed the situation that our client application based on QuickOPC (5.52.164.1) fails, due to a license error:

An OPC-UA operation failure with error code -1 (0xFFFFFFFF) occurred, originating from ''. The inner exception, of type 'OpcLabs.BaseLib.Licensing.LicensingException', contains details about the problem.
Inner exception occurred: Not allowed to run by the license "Multipurpose". You might be using a trial license, and the version of the software you are using is obsolete. Obtain a recent version to resolve this problem.
Component name: "QuickOPC", license IDs: "Multipurpose", version number: 552, release date: 13.02.2018, trial validity: 210 days, option name: "EasyUAClient".


But LicenseManager.exe on the same system shows that our the license is valid and active.

My questions:
- What is the cause for this difference?
- How can we be sure that out applications use the license that was deployed to the system?
