Hi, sorry for naive question... Have searched forums and only come across one other similar post. I have an OEM version of Windows XP Pro. I have copied the entire contents of the disc across to a folder on my C: drive, that I have named "XP_source_folders". When I run nLite, whether I point it at the disc itself, or I point it at this folder (or indeed, when I point it at any of the sub folders!), I always get a pop up that says: "Make sure that the selected folder or drive contains the 'i386' or 'AMD64' directory and proper Windows installation files..." etc What am I doing wrong? I have only ever seen an 'i386' folder in my C: drive itself (from a previously installed, different version of Windows XP). Do I need to copy this folder into my "XP_Source_folder" too? (This doesn't make sense to me, as that would be old installation and new installation folders mixed together). Confused! Any help much appreciated. Cheers Giles
