Hi, I am trying to make a slipstreamed setup disk for Win XP Pro for my laptop using nLite. I cannot install Win XP Pro without installing my SATA drivers. nLite succesfully adds WinXP Pro, SP2, and my SATA drivers; however, when the program is saving to disk I get the following message: Error P-The process cannot access the file D:\XP_source\syssetup.dll because it is being used by another process. The program then crashes. D:\XP_source\ is the path to the installation file. D: is a second drive on my laptop, not the system drive, so there is no way the file is being used by any programs. Any ideas how to fix this? THanks, Paul Romano HP Pavilion dv8380, 2GB RAM, 2x120MB hard drives, currently running Win XP MCE SP2. I am trying to upgrade with an old copy of Win XP Pro SP1 Upgrade.
