Hello all: I'm trying to Slipstream an XP Pro disk. The base disk is a SP1 desk and when I try to add SP2 to the package I get the follow message: "Integrated install failed. The language type or platform for the destination directory and Service Pack 2 must be the same." I'm confused since they are both English (US) and I have the correct platform. Any ideas on what is causing this? Thanks, Ken
