In the case several years ago when it worked, I took an off-the-shelf retail MS Windows XP SP3 CD, chose a whole bunch of configuration options, burned an nLite'd ISO, installed Windows by hand in an attended fashion, and "Program Files" was successfully renamed. In the case today where it is not working, I tried to take an off-the-shelf retail MS Windows XP SP1 (not SP3, but SP1) CD, chose a bunch of similar options as before but added the slipstreaming in of the SP3 binary, burned an nLite'd ISO, installed Windows by hand in an attended fashion, and "Program Files" is still "Program Files" despite my choice to the contrary. Neither of the CDs were what I would consider "unattended" CDs, though I don't really know what that means. They weren't OEM or otherwise special CDs, just standard off-the-shelf retail MS Windows XP Professional discs. I imagine that they can be run in some sort of unattended mode somehow, though I've never tried to do that. So, I think the answer to whether I'm doing everything in 1 go is "yes", and I think the answer to "is the starting CD unattended" is "no", but I'm not 100% sure I know what you mean by those -- apologies, I'm a n00b to these forums and have only used the nLite tool a little bit. One thing I have not tried is to first slipstream the SP3 into the SP1 cd, then burn an ISO, and then use that as a "SP3 CD" from which to start choosing options like renaming "Program Files". I'll probably end up trying that tomorrow unless somebody has a better idea. I went back and looked at what version I was using a few years ago, and it looks like I was actually using the same 1.4.9.1 version from Sept. '08 both then and now. So, the question I guess is no longer "did something change in the last few years?", but more "this worked for me starting from an SP3 CD before, but is not working for me now starting from an SP1 CD, anybody know why not?"
