    Hi, just guessing, are you using 127.0.0.1 (or localhost) to connect to the database also on the new PC? Also, have you checked that you can reach the database with MySQL workbench?

          Is the ODCB connection created on 2nd computer? Also with mysql connector you need Visual C++2015 distro.

              @JSher No, I just tried to print the error on a label with db.lastError() and the output is: "[Microsoft][Driver Manager ODBC] Nome origine dati non trovato e driver predefinito non specificato. QODBC3: Unable to connect"

                Sorry what I meant was did you configure the ODBC data source on the 2nd computer.

                Like this:

                  No, this procedure is necessary for each device that must use the application?

                    Its connecting to an OBDC entry in windows by the looks of it. I do not use ODBC much but the way I understand it is you have to make the entry on each machine....Thats why I use the standard mysql connector, then you do not. I could be off:)
