hi, I find a solution,
Pb was Vss services. it was launched but in fact, there was an error (sorry it'in in french) :
Erreur du service de cliché instantané des volumes : l'enregistreur de cliché instantané ContentIndexingService a appelé la routine RegQueryValueExW qui a échoué avec le statut 0x80070002 (converti en 0x800423f4).
I make investigation and solution was to delete a key in the registry base at : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\Catalogs\Visio].
So now it works... thanks for your help.
Regards,
