OPCDA: Class not registered Exception

Replied by support on topic OPCDA: Class not registered Exception
Hello,
I have some questions.
1. Is the target OPC server located on the same computer as your client app, or on a different computer (remote)? Is "MyIp" the proper name for the computer where the server is located?
2. Have you tried to read from some other OPC server, located on the same computer as the Matrikon simulation server?
2a. If yes, what were the results?
2b. If not, can you please test that, and let us know the results?
3. Which version of Matrikon simulation server you have installed?
4. You wrote "we no longer read data", but the error indicates that the methods called was for node browsing. Please clarify.
Best regards

Hello,
We have an application that reads data from server using QuickOPC version 5.54.1151.1.
After updating to version 5.63.215 we no longer read data, the error is:

We have updated OPC Core Components to the latest version.
We also get the same error with the OPCDA Demo Application installed with QuickOPC-2022.1.
With rollback to 5.54.1151.1 it's working properly.
Do you have any advice ?
Best regards,
Stefano
