"IBO40CRT_D6.bpl" ??? I did not think an '_D6' library existed. Is
this a demo installation or full source?

Presumably Delphi6, what version of IBO and what operating system?

Any chance you have a mix of IBO versions installed? Try uninstall
and reinstall of the latest IBO version.

Just some thoughts. It is difficult to tell from the information
provided. If none of the above resolve the problem, it may help to
post more information about the query itself (is the TIB_Connection
instance connected and the dataset prepared or active when the error
occurs?).
