The 'ProgramFilesDir' one is my main concern. But other, little, things such as 'AutomaticUpdates' That's interesting, because those seemed to install without issue. My audio, video and network devices are installed whereas, when I do an install of the boxed XP, they are not. nLite must have added them another way? Where are these documented as valid entries? They don't show up in ref.chm. This may be your problem... <{POST_SNAPBACK}> I got those entries from here. They worked for my XP SP1 install a while ago. Has support for these flags been discontinued? J.
