Error messages in the Delphi IDE

Question / Problem

When I move to certain folders (e.g C:\Windows\assembly) Delphi displays an error message like: "Could not get IShellFolder2 interface for current folder". How can I prevent this?

Answer / Solution

This message is triggered by a handled excpetion. In the default configuration, RAD Studio stops on all exceptions, if handled or not. The end-user will not see errors like this for handled excpetions. Using exceptions for error handling is common in modern programming languages.
We recommend turning off this option:
"Tools > Options > Debugger Options > Language Exceptions > Notify on Language Exceptions".
