I get an error on 1st boot when trying to call WIHU from the cd. The error is can't find path \software\wihu\wihu.exe, yet when I double click the cmd file on the cd/dvd it works fine. Therefore is it the way i'm calling the cmd file from winnt.sif or the cmd? wihu.cmd (located %CDROM%\$OEM$\$1\install) cmdow @ /HID @echo off IF EXIST D:\CD.txt set CDROM=D: IF EXIST E:\CD.txt set CDROM=E: IF EXIST F:\CD.txt set CDROM=F: IF EXIST G:\CD.txt set CDROM=G: IF EXIST H:\CD.txt set CDROM=H: IF EXIST I:\CD.txt set CDROM=I: IF EXIST J:\CD.txt set CDROM=J: ECHO. start /wait %CDROM%\Software\wihu\wihu.exe /skiprestart /skipsettings /usecurrent /autologon ECHO. EXIT winnt.sif [GUIRunOnce] %Systemdrive%\install\wihu.cmd
