OK...I am a new member..and this place is awesome. For my first attempt with Slipstreaming, I took a XP Pro CD, and slipstreamed SP1a. I then Slipstreamed Sp2 RC1.... Everything worked perfectly for the unattended installation EXCEPT...during the initial file copy from the CD(the blue screen), i get the following error: Setup cannot copy the file: And it happens several times, with the following files: iac25_32.ax ir41_32.ax ir41_qc.dll ir41_qcx.dll ir50_32.dll ir50_qc.dll ir50_qcx.dll ivfsrc.ax When it does, I hit ESC, and it skips the file. The rest works perfectly. Any ideas how to correct this? I would love to have the PERFECT unattended install CD
