Hello all, I am new here, but have been in the IT industry for years. Anyway, I was hoping someone from this board could help me out with nLite. I have used it once or twice in the past to integrate drivers into an OS, but never for anything beyond that. Right now I just need some help integrating a service pack into an OS. I receive an error the last few times I've attempted. Here's some more information: My OS: Windows XP Pro SP3 What I'm trying to do: integrate SP3 onto a Windows XP Pro SP2 CD-ROM. nLite reads my disc fine and copies its contents to my hard drive for editing, but when I go to the next step and try and integrate SP3 into my project I always get an error. It says that not all the files needed for an integration or slipstream are present. Basically what I did was download SP3 from Microsoft's website and extract its contents onto my hard drive. After that I told nLite where the i386\update\update.exe file was and then after a few seconds I receive the error I mentioned earlier. Anyway, if anyone can help me out I would greatly appreciate it. Like I said, I don't know much about this program and it's very possible that I've made a stupid mistake or something. Thank you!
