Hi Cre8tive, Can you share on how you fixed this? I'm very interested in getting this integration to work on an XP install as I'm having the same problems. I have put this iin my winnt.sif file. [GuiRunOnce] %systemdrive%\install\start.cmd -0-0-0- And put this in my start.cmd file ECHO install Office XP Professional ECHO Please wait... start /wait %systemdrive%\install\Applications\OfficeXP\setup.exe TRANSFORMS=Unattended.MST /qb-
