http://www.inachis.com/download/index.php In fact E-backup does not settle... It makes party of my Install.bat with the order: start/wait %systemdrive%\Install\Ebackup\ebackup.msi/qn REBOOT=Suppress Install.bat is ordered by cmdlines.txt: all this master key well except E-backup.msi which does not settle. In "cmdlines" I have also my clean.bat which plays its role at the end, with the reboot of the PC! After the reboot of the PC, with the loading of my parameters, E-backup seek its files of installations which it does not find normal... parcqu' it would have to settle in T-12.
