Ok exact problem is when you try to add remove anything in installation, I mean integrate drivers or remove components (at least they are which I have tried), nlite exits without any message or error. Simply dissapears. I slipstream dx9 ie6 mp9 and all hotfixes in w2000 plus my hacked system files regs and fixes for w2000. I don't include any third party app or any net framework. Nlite exits when I try to remove components or install drivers... Only that... annoying ANNOYING fact EDIT By the way, all this was made on a clean-formatted-wxp sp2, with only nlite, ultra iso and net framework 2 installed (without any net framework or system update) EDIT2 I hope it's for help to some people, specially you sunnyboymark: I found MY problem. After trying so many times with nlite 1.0.1 final, I made the conclussion that when you try to remove some components nlite crashed. I had hacked sfcfiles.dll to remove file protection, and THAT was the problem. I downloaded nlite 1.0 final, and it gave me the solution, because before exiting it displayed this error message "Wrong compression on sfcfiles.dl_" (or something similar, ver 1.0.1 didn't display that message...). This was due to I renamed sfcfiles.dll to sfcfiles.dl_ instead of makecabbing it. Now I had compressed it and It works like charm. I hope the nlite 1.0.1 exit errors are due to wrong compression on some archives, and the fact that that version of nlite doesn't display the right error message.
