Check if there is a Download missing driver files link at the bottom of the data source settings area.

The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.
You can specify your drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.
To connect to an existing SQLite database, specify a file path to the database file in the File field.
