OPC-UA Client: Exception on TCP/IP

The 2018.1 version (Beta) has currently the functionality differences described here: kb.opclabs.com/What%27s_new_in_QuickOPC_2018.1 . And, there is a supposed fix for a similar problem (hang) you had.
Your license should be OK. If it were installed but not OK, the error message would be different. But this error test indicates that no license is being "seen" by the component. Have you installed it on the target computer? Using License Manager, or by some other means?
Thank you

You can use it but it is more risky than with released versions (has not gone through final testing).
Your license covers it as well.
I expect the release be during the coming February.

I know I have already referred you to a newer version, but in fact we have made yet another fix that was for an issue very similar to yours. The fix is currently only available in the "alpha" version of upcoming QuickOPC 2018.1 version. I will send you a private link to download it, to the email you have used to register with these forums. I would appreciate if you can give it a try.
Best regards

Please just clarify before I respond in full: The problem is not in the error itself, but in the fact that the application hangs.
Is that correct?

I try to update the QuickOPC to 2017.2 but the error persist.
then I try to debug step by step my application:
when fault the TCP/IP(unplug cable) connection from my application and OPC UA Server (that is in another PC) the EasyUAClient istance are freezing. If I try to call a method of object it lock my program.
So I try to use the EasyOPC-UA Demo Application and there is the same error:
I try to read and subscribe a node-id on my OPC-UA Server and it works fine.
After I unplug cable TCP/IP and retry to read the same node-id and it freeze the application(see the attachment).
Can you help me please?

You need to re-build your application with the new assemblies. And, although we try to avoid that, there may be some slight API changes. For list of versions and the changes in them, see kb.opclabs.com/Versions . Click on the links under "Key Changes - What's New" to see the details.
Beware of the .NET Runtime requirements: QuickOPC 5.35. ran under .NET Framework 4.5 to 4.6, while the minimum for QuickOPC 2017.2 is .NET Framework 4.5.2.
If the new version resolves the issue and you are not covered by the maintenance agreement (which gives you title to new versions free of charge), we will provide you with a discount on the version upgrade.
Best regards

Hello,
How can I do to upgrade the QuickOPC? Is it only necessary to update the dll in my Visual Studio project?
