Error: "Invalid parameter "

Error: "Invalid parameter "

Hello.

I'm using the SQL-Server dbExpress, version 9.3 with Delphi Athens.

On my development computer the connection with the database is workink perfectly.

However, when I tryed to execute the application in a different computer I get this error message "Invalid Parameter"

I already put the dbexpsda41.dll on the same folder of the application.

Please, can you help me to identify what I'm missing?

Thank you.
