This has been driving me crazy for a while now. I nLite a clean XP Pro version and subsequently run DPs_BASE to integrate the driver packs. When I fire the result up in VMWare (or a real machine), I get the error message: 'Windows cannot find 'd:\OEM\WatchDriverSigningPolicy.exe' When I slipstream the DPs onto the clean XP version, everything works fine, and the drivers are properly extracted and installed. So, I figure this might be nLite related rather than DP_BASE related. It seems to me that presetup.cmd is either not being invoked at all or not finding the proper files. winnt.sif, presetup.cmd, et.al. all look OK to me (though I am a noob at this...), so I thought something might be wrong in the setup.exe area. I followed Pyron's instructions here, but with no apparent success. Nobody seems to experience this, so I must be missing something fundamental. But what? Any help will be received with gratitude.
