Unfortunately I have the same problem ...
Base - DPs_BASE_7052.exe
Mass Storage - DP_MassStorage_wnt5_x86-32_7092.7z
I am taking an SP1 disk, rolling up with SP2 and hotfixes, removing the games, and making it an unattended install in nLite. I then integrate the drivers using the base program.
I have the same message as the user describes above.
Is there anything else I should be trying? (I am currently going back to basics and integrating into the original SP1 disc as an experiment)
Cheers
CD
