After somme problems, i had to manually uninstall the Joodb Component.

Reinstalling , 2 messages in the Installation display:

Install sucessful, but red message: Error in administration construction menu.

Effectively, impossible to have access to the Joodb submenu in the Component Menu. Then impoosible to install new databases and to modify different views and forms ...

Thank you for some help
