"DetachedPrograms" not working

[arpoadhikari]

I just want to execute a simple EXE file at T-39 stage. So I added the following code in WINNT.SIF.

[GuiUnattended]
    AdminPassword=*
    EncryptedAdminPassword=NO
    OEMSkipRegional=1
    TimeZone=190
    OemSkipWelcome=1
    DetachedProgram="%systemdrive%\Run.exe"

But the problem is that, the file "Run.exe" is not executing.

Location of Run.exe is "<CDROM>\$OEM$\$1\Run.exe".

This file(Run.exe) was created by compilng a simple .BAT (Batch) file.

Code of "Run.bat" is --

ECHO WELCOME TO WINDOWS XP
ECHO Thank You
PAUSE
EXIT

I viewed the similar topic on this forum, but it did not help me.

Can anyone help me to execute an application at T-39 stage? and

What are the limitations of "DetachedPrograms" ?
