Ok, So I did as described here, . Install WAIK SP1 . Install vLite 1.2 . Download Windows6.0-KB936330-X64-wave0 5 languages . Select Business profile ( french student msdnaa version 6.0.6000.16386 ) after file copy . Only enable slipstream and make iso options Then the slipstream starts, and ... stops ( have to wait about 45min ). With Failed. No changes were saved as status. I can click Back, Next Exit but the sp1 integration doesn't want to work. I tried to d/l a multilingual ( wave1 ) vista sp1 > same message. I tried to choose BusinessN profile > same message. Any help ? Thanks !
