Although I was not able to reproduce the issue, I found that a synchronization statement is missing, and that it is a likely cause of the problem.

This is now fixed in the currently posted QuickOPC 2018.1 (on our Web page, and also in the NuGet packages). It is version/build 5.52.91 or later.

Please rebuild your project with it and re-test.

Best regards

Hello,

Thank you very much for the additional information. It is very helpful. From the call stack, it looks like a bug in QuickOPC. Unfortunately I cannot determine more details until next week when I am back in the office.

Please bear with me and I will respond then.

Best regards

Thank you again. I do not know what is causing the problem, but below are some thoughts and hints.

1. The log you have sent contains two suspicious things: One is

An exception occurred in the OnAfterInstall event handler of System.ServiceProcess.ServiceInstaller.
System.ArgumentException: Attempt to add existing key into a dictionary."

The other is

An exception occurred in the OnAfterInstall event handler of System.ServiceProcess.ServiceInstaller.
OpcLabs.EasyOpc.UA.OperationModel.UAException: An OPC-UA operation failure with error code -1 (0xFFFFFFFF) occurred, originating from ''. The inner OPC-UA service exception with service result 'BadCertificateUntrusted' contains details about the problem.
The inner exception OpcLabs.EasyOpc.UA.UAServiceException was thrown with the following error message: Self Signed Certificate is not trusted.
IssuerName: CN=InstallUtil.exe, DC=[HIDDEN AS WELL] = BadCertificateUntrusted.
+ The error occurred while checking the (client) application instance certificate. The certificate generator path was "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Opc.Ua.CertificateGenerator.exe"..


Especially for the first one, it would be really useful to know the call stack (where it is coming from). Can you put try/catch block around the call to EasyUAClient.Install(), and log the call stack in case of an exception?

2. It would be also good if you can hook to EasyUAClient.LogEntry event before calling EasyUAClient.Install(), and then log all the message it generates.

3. Although what I will describe in this point is not probably causing the issue, it is a problem as well and I suggest that you resolve it. The problem has to do with naming of the generated certificate. If you do not set the name explicitly (more about it later), QuickOPC generates a name automatically, using information such as the running executable's name. The certificate name is used for lookup: When the certificate is generated, and the application is run the next time, it looks for the certificate and tries to reuse it.

In you case, using the automatically-generated certificate name will lead to problems. I can see that although your application's name is OpcToXml.exe, the name of the certificate generated by EasyUAClient.Install() is "InstallUtil.exe" - because that's what the running program at that time is, and "OpcToXml.exe" is just hosted by it. But when you will later run the actual OpcToXml.exe, it will look for "OpcToXml.exe" certificate (or possibly other auto-generated name - but not InstallUtil.exe".

In order to prevent this from happening, set the certificate (application) name explicitly in *both* the installation part, and the normal execution part, *before* calling EasyUAClient.Install() or any other of its methods. The process is described here: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...%20Instance%20Certificate.html . An example in C# for that looks like this:
// This example demonstrates how to set the application name for the client certificate.
 
using System;
using OpcLabs.BaseLib.Instrumentation;
using OpcLabs.EasyOpc.UA;
 
namespace UADocExamples._UAApplicationParameters
{
    class ApplicationName
    {
        public static void Main1()
        {
            // Hook static events
            EasyUAClient.LogEntry += EasyUAClientOnLogEntry;
 
            try
            {
                // Set the application name, which determins the subject of the client certificate.
                // Note that this only works once in each host process.
                EasyUAClient.SharedParameters.EngineParameters.ApplicationParameters.ApplicationName = 
                    "QuickOPC - CSharp example application";
 
                // Do something - invoke an OPC read, to trigger some loggable entries.
                var client = new EasyUAClient();
                client.ReadValue("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853");
 
                // The certificate will be located or created in a directory similar to:
                // C:\Users\All Users\OPC Foundation\CertificateStores\UA Applications\certs\
                // and its subject will be as given by the application name.
 
                Console.WriteLine("Processing log entry events for 10 seconds...");
                System.Threading.Thread.Sleep(10 * 1000);
 
                Console.WriteLine("Done.");
            }
            finally
            {
                // Unhook static events
                EasyUAClient.LogEntry -= EasyUAClientOnLogEntry;
            }
        }
 
        // Event handler for the LogEntry event.
        // Print the loggable entry containing client certificate parameters.
        private static void EasyUAClientOnLogEntry(object sender, LogEntryEventArgs logEntryEventArgs)
        {
            if (logEntryEventArgs.EventId == 161)
                Console.WriteLine(logEntryEventArgs);
        }
    }
}

1) Which QuickOPC version/build are you using?

It's the nuget package version 5.52.75

2) The certificate needs to be installed into the trusted store. Does your customer run the installer under administrator account, *and* with elevated privileges? (the behavior of Windows depends on UAC settings in this respect; your computer may be set differently than customer's).

They are 'running as administrator" - i assume this must mean they are an administrator...

On my PC the certificate ends up in c:\program data\OPC Foundation\CertificateStores\UA Applications\certs - i'll check what they have in there..

3) Is the installer in an executabel separate from the actual application, or are they "in one"?

They are installing the exe I have produced using installutil (in .net 4.5) folder
with...

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe OpcToXml.exe


4) Do you set the ApplicationName parameter in EasyUAClient shared parameters either in the installer project, or in the actual app?

No
