I looked through the forum topics, and wasnt able to find a solution to this problem, so here goes. I've successfully slip streamed sp3 + later updates into an Office 2003 admin install. I tested it, everything installed just fine. and ran just fine. Burned the admin install folder to a cd, uninstalled office, then tried to install from the cd The progress bar showed about 50% when I was prompted to insert the Office 11 cd. I was not prompted for anything like that during the install from the hard drive. Of course, I hit cancel, and the installer did a rollback. What am I missing? Any pointers will definitely be appreciated
