The file should be alongside the final executable of your app. This should work in Delphi as well.

TCP errors usually come from networking issues or server issues and are not caused by problems in the client. Have you verified these? Does the TCP error indicate a specific number?

Anyway, if there is a reproducible error you are struggling with, and all other attempts to find the reason fail, a detailed troubleshooting will be necessary. Instructions for that are here: kb.opclabs.com/Collecting_information_for_troubleshooting .

What you are describing is not an error reported through QuickOPC API, but a warning message in generated log entries. Warnings usually do not need attention unless there is a real problem as well.

1) What is the actual problem you have?
2) Which OPC server are you communicating with?
