(I'm an N-Lite newbie, please bear with me. I did perform a forum search for this problem, though.) I'm attempting to slipstream XP64 Pro + SP2 (plus more stuff, probably, but I'm just trying this much now as a test). I've copied the entire installation CD to a local folder on C:\, and have downloaded the SP2 update from Microsoft. Details: OS: Windows XP Professional x64 Edition SP1 (r.2.3790.1830) Update file: WindowsServer2003.WindowsXP-KB914961-SP2-x64-DNU.exe Update file: WindowsServer2003.WindowsXP-KB914961-SP2-x64-ENU.exe Hardware: AMD Athlon 64, 2.22GHz, 2G RAM, 95GB free on HDD N-Lite v1.4.6 In N-Lite I have chosen the local folder with the XP64 files, plus the SP2 update, and selected the option to create an ISO; that is, I've taken all steps up through the end of: http://www.nliteos.com/guide/part1.html N-Lite begins extracting files to a temp directory. When it gets to the file 'amd64\spconw.ch_', it halts with a "File is corrupt" error. I have recopied that file from the XP64 installation CD into the local XP64 folder, and tried again. Same result. Any ideas? Suggestions? Thanks!
