I installed the newest version 1.4.5 but I am unable to do anything with it. I followed the guide and copied Windows XP Pro SP2 into a new empty folder on desktop. Then I launched nLite and chose that folder with XP in it as a source. nLite then takes 10-15 seconds and lists data about the OS (version etc...) And then it completely freezes. End of story. I tried not only this newest version but the older ones too. I also tried different Windows XP CDs and I tried to install nLite on different PCs. Nothing helped; always the same problems and freezing. Am I missing something? Please help me out... Yes, .NET Framework 2.0 SP1 is installed. Thank you all
