Hello, I used nLite for a while and it works fine. Recently I bought a new laptop from Dell which has a OEM activated Vista Home Premium (Traditional Chinese) DVDROM. Yesterday I downloaded SP1 full package (Windows6.0-KB936330-X86-wave1.exe) and tried to slipstream SP1 into it with vLite RC. I only checked "slipstream ServicePack" and "make bootable image" in the task, after vLite copied all files on OEM DVD and asked SP1 file location, it starts slipstream, but stopped after about 30 minutes it started slipstream task, only show a message to indicate something was wrong, without detail information. Is there a log that I can see what's wrong or post to here for discussion?
