Hi Alberto,
B1DE doesn't support the silent installation, because it's installer will always popup the forms.
Note that the ARD file only "hints" B1 that this is a silent installation, your installation application must detect that the silent installation arguments were used and then proceed to perform a silent (unattended) installation. You can use the InstallParam.zip file included so that any parameters your application needs can be extracted from it.
B1DE installation wizard will have to be changed in order to support the silent installation.
Best regards,
Pedro Magueija
