Hi 2cansan,
The real link would be easier, no need to hide it
yy_1-postconfig.script
DirMove - Failed to move directory [%BaseDir%\Target\Win7PESE\Program Files] to: [%BaseDir%\ISO\WIM\boot.tmp]: Unknown error
Difficult to know the reason for this DirMove failure in postConfig

, there is no problem for most.
Without having to rebuild all, you can retry the finalization and the creation of the ISO :
In PostConfig use the button "Create new Target Image and ISO"
if you have the same thing, can you try to change the line 187:
for moving the folder manually in windows and see what happens.
DirMove,"%targetdir%\Program Files",%BootTMP%
=>
Message,"Move manually '%targetdir%\Program Files folder to %BootTMP%"
//DirMove,"%targetdir%\Program Files",%BootTMP%
