I have a WinXP X64 installation CD. I wanted to integrrate SP2 into it.
So, I used nLite for that purpose. After creating ISO when I was trying to install that then I found this error

And in my slipstreamed CD I found a I386 folder. But, that folder wasn't here before integrating SP2.

Have I done anything wrong while slipstreamed?
I slipstreamed SP2 from XP 64 bit edition.
